Letter from the Forensic Science Service
In response to your letter of 20 July 2000,
I enclose a submission on behalf of the Forensic Science Service
(FSS).
The FSS acts as Custodian of the National DNA
Database and uses genetic data to provide scientific support to
the police in the investigation of crime. There are now a number
of other organisations that also contribute to the National DNA
Database and will thus have collections themselves of related
genetic data. I can provide you with a list of these if necessary.

THE NATIONAL
DNA DATABASE
1. Police powers under the Police and Criminal
Evidence (PACE) Act 1984 were extended from 10 April 1995 by the
Criminal Justice and Public Order (CJ&PO) Act 1994. This allowed
the police to take non-intimate samples without consent from persons
in police detention or custody who have been charged with or told
they will be reported for committing a "recordable offence"
(an offence subject to a term of imprisonment), and from persons
convicted of a recordable offence after 10 April 1995 if they
have not already provided a sample for that offence. It also allowed
the police to take a non-intimate sample from persons not in police
detention or custody, if one has not previously been taken, or
the sample is unsuitable or insufficient for analysis, provided
it is obtained within one month from the date of charge or conviction
or notification that the sample is unsuitable or insufficient
for analysis. They were further given the power to use information
derived from these samples to check against information derived
from other samples held on behalf of the police in connection
with or as a result of the investigation of an offence. The powers
were then extended by the Criminal Evidence (Amendment) Act 1997,
to allow the taking of non-intimate samples without consent from
individuals who were convicted for a sex, violence or burglary
offence prior to enactment of the CJ&PO legislation on 10
April 1995, if they are still serving a period of imprisonment.
2. Home Office Circular 16/95 provided advice
on the operation and use of a new National DNA Database (NDNADB)
for England and Wales, based on DNA profiles obtained from non-intimate
samples (mouth swabs/buccal scrapes and hair samples with roots
taken under PAC as amended by the CJ&PO) and profiles from
biological material recovered from scenes of crime.
3. The FSS has been the Custodian of the
NDNADB since its inception, under the terms of a Memorandum of
Understanding with the Association of Chief Police Officers (ACPO).
4. The FSS was also initially the sole supplier
of DNA profiles to the NDNADB. It remains the principal supplier,
but there are now other suppliers in the public and private sectors.
5. The data on the NDNADB and the samples
obtained for DNA profiling are the property of individual police
forces.
6. The NDNADB is used by the Custodian to
provide intelligence information to assist the police in the investigation
of crime by checking all new additions to the Database against
the profiles currently held from CJ samples and samples from unsolved
crimes.
7. DNA profiles and the associated demographic
data are removed from the NDNADB if the Custodian is notified
that the case against an individual has been discontinued, or
they have been acquitted or died. Profiles retained long term
on the NDNADB thus relate only to individuals who have been cautioned
or convicted.
8. When profiles are removed from the NDNADB,
the associated samples are destroyed as soon as practicable thereafter.
Q1A. What current projects involve collecting
genetic information on people in the UK?
9. The National DNA Database (NDNADB). There
are also subsidiary databases associated with the NDNADB that
do not hold both genetic information and details of the individual
from whom this was derived, but which could provide links to collate
this information (eg the Custodian's match reporting and acquittals
databases and the FSS/supplier's submissions and sample storage
databases).
Q1B. What other projects are about to start?
10. None.
Q1C. Are there collections of material (eg
tissue samples) that could be used to generate databases of DNA
profiles?
11. All buccal scrapes or rooted hairs obtained
from individuals for DNA profiling for NDNADB purposes are retained
by the FSS as a supplier of profiles to the NDNADB, and other
suppliers, for as long as the DNA profile is retained on the NDNADB,
pending the need to revalidate an initial analysis or to allow
the profile held on the NDNADB to be upgraded should the technology
change. Some of the intermediate analysis products are also retained.
Q2A. Why are these genetic databases being
assembled?
12. To provide the police with intelligence
information to assist with the investigation of unsolved crimes.
Q2B. How are these activities funded?
13. The costs of the Custodian of the NDNADB
are recovered by charging the police and suppliers of DNA profiles
to the NDNADB for the services provided.
14. The costs of the FSS as a supplier of
profiles to the NDNADB are recovered by charging the police for
the services provided.
Q2C. What practical considerations will constrain
developments?
15. Funding; the availability of robust
and reliable new equipment/technology and competent staff resources;
Government and police policy; legislation and case law; public
opinion.
Q2D. Are there alternative ways of fulfilling
the objectives?
16. No.
Q3A. What is the genetic information that
is being collected?
17. The profiles on the NDNADB are Short
Tandem Repeat (STR) DNA profiles. Until 1999, they comprised data
from six STR loci (the SGM loci: HUMTHO1; D21S11; D18S51; D8S1179;
HUMVWFA/31A; HUMFIBRA(FGA)) and the amelogenin sex marker. Subsequent
profiles have contained additional data from four further STR
loci (the SGM Plus loci: SGM loci + D19S433; D16S539; D2S1338;
D3S1358). As far as we are aware, none of these STRs code for
identifiable gene products or physical characteristics.
Q3B. How is it being stored and protected?
18. The main data are stored electronically
by the Custodian on a purpose built National DNA Database. Access
to and use of the Database is controlled in line with the Data
Protection Act, other Home Office IT Security regulations, and
in compliance with the international ISO 9001 quality standard
and the national M10 quality standard of the United Kingdom Accreditation
Service (UKAS).
19. The subsidiary databases held by the
Custodian and suppliers are on restricted access, password controlled
stand alone computers.
Q4. How do the organisations involved see
their responsibility regarding privacy; consent; future use; public
accountability; intellectual property rights?
20. The samples and the information derived
from them are obtained, stored, used and destroyed in accordance
with legislation and Home Office and police requirements. The
FSS is registered under the Data Protection Act. It is also registered
by BSI to the ISO 9001 standard and accredited by UKAS to the
M10 standard for its DNA profiling services.
21. The Custodian of the NDNADB ensures
that the data on the NDNADB is used only for the purposes for
which it was obtained, that access to the data is controlled and
that it is retained for only as long as required, in accordance
with PACE (as amended), HO Circular 16/95, the Memorandum of Understanding
with ACPO and data protection legislation.
22. The FSS as a supplier of data to the
NDNADB, and other suppliers, have to meet strict performance and
procedural standards set by the Custodian to ensure that, as far
as practicable, the profiles submitted are correct and attributed
to the appropriate individual. The Custodian and UKAS monitor
compliance with these standards.
23. The efficiency and effectiveness of
the NDNADB is overseen by a National DNA Database Board which
is jointly chaired by a representative of ACPO and the Chief Executive
of the FSS. The expansion of the NDNADB (see below) is being monitored
by the Home Office.
24. The NDNADB and its logo are registered
trademarks.
Q5A. How do they see their activities in the
area of genetic databases developing in the future?
25. The purpose of the NDNADB will remain
largely the same. However, the Government and the police have
recognised the immense benefits of the NDNADB to law enforcement
and have provided a substantial increase in funding to allow it
to grow to such a size that it will contain the profiles of virtually
all active criminals within the next three years.
Q5B. What advances in sequencing, screening
and database technology are they anticipating?
26. There will be on-going technological
improvements in the way the profiles are obtained and the NDNADB
is managed. It is also anticipated that developments in DNA technology
and miniaturisation will lead to more information being obtainable
from tissue samples and more quickly than at present. The advent
of "chip technology" could also mean that the technique
could be de-skilled sufficiently for personnel to undertake analysis
with relatively little training. Furthermore, such analysis may
be undertaken outside the laboratory environment. The interpretation
of the evidence in the context of the case will remain a skilled
procedure, although the development of expert systems will facilitate
this.
Q6. What lessons should be learnt from genetic
database initiatives in other countries?
27. The UK has taken the lead in this area.
We have provided support to a number of other countries to assist
them in the development of their own systems.
OTHER FSS DATABASES
28. The FSS has an active research programme
to develop new ways of obtaining and using genetic information
to support the police in the investigation of crime. The FSS also
maintains databases of genetic information that it uses in providing
intelligence information to the police and evidence for the courts
and the FSS maintains some other databases of genetic information
for non-police customers that are held by consent of the donors
of the DNA samples.
Q1A. What current projects involve collecting
genetic information on people in the UK?
29. Single Locus Probe (SLP) database: holds
SLP profiles from undetected crimes and from individuals whose
DNA was used to secure a conviction (as allowed by the legislation
at the time).
30. Police Elimination Database: holds STR
(SGM Plus) DNA profiles from buccal scrapes provided voluntarily
by police personnel.
31. FSS Staff Elimination Database: holds
STR (SGM Plus) DNA profiles from buccal scrapes provided voluntarily
by FSS personnel.
32. Single Locus Probe (SLP) frequency database:
holds SLP restriction fragment length polymorphisms derived from
samples of known ethnic origin provided voluntarily by staff and
other organisations and from casework.
33. HLA, DQa and STR allelic frequency
databases: holds HLA, DQa and STR DNA profiles derived
from samples of known ethnic origin provided voluntarily by staff
and other organisations.
34. Mitochondrial DNA Population databases:
hold mitochondrial DNA sequences from samples of known ethnic
origin provided voluntarily by staff and other organisations and
from casework.
35. Red Hair Prediction Database: holds
DNA sequences from samples provided voluntarily by staff and related
individuals.
36. Crisis Check Database: holds STR (SGM
Plus) DNA profiles from buccal scrapes obtained with the consent
of non-police customers.
Q1B. What other projects are about to start?
37. Development of frequency databases for
the STR loci in the Applied Biosystems Cofiler and Profiler profiling
systems and the Promega Powerplex systems.
38. Extension of mitochondrial DNA population
databases to other racial groups.
39. Development of other commonplace characteristic
databases to help identify possible phenotypic traits (eye colour,
facial characteristics, weight, height, etc) and hence intelligence
information to the police from biological material left at scenes
of crime.
40. Development of assays based on single
nucleotide polymorphisms (SNPs)specifically for use in
microfabricated array format for paternity testing (with c50 loci),
as Y chromosome markers and as new mitochondrial DNA markers.
SNP assays may also be used for commonplace characteristics work
(see above).
Q1C. Are there collections of material (eg tissue
samples) that could be used to generate databases of DNA profiles?
41. Police and Staff Elimination Database
samples: stored as buccal scrapes; retained for as long as the
STR DNA profiles are retained on these databases.
42. Miscellaneous samples of extracted DNA,
blood, saliva, semen, vaginal swabs, buccal swabs, faeces, hair
and urine samples, voluntarily donated by staff and other organisations
for various research purposes, the development of frequency/population
databases and the validation of new techniques.
Q2A. Why are these genetic databases being
assembled?
43. The Single Locus Probe database was
used to provide the police with intelligence information to assist
with the investigation of unsolved crimes.
44. The Police Elimination Database is used
to check for the possibility of contamination by police personnel
in the collection or handling of material obtained for the NDNADB.
45. The Staff Elimination Database is used
to check for the possibility of contamination by FSS staff in
the collection, handling or analysis of material obtained for
the NDNADB.
46. The DNA frequency databases and the
mitochondrial DNA population databases are used to provide information
on the likelihood of a DNA profile obtained from material left
at scenes of crime matching by chance DNA profiles from individuals
in a specified population, and hence in the interpretation of
casework findings for the courts.
47. The Red Hair Prediction Database was
produced to help in the development of a DNA sequence polymorphism
based test aimed at providing intelligence information to the
police about the possible physical appearance of an offender from
analysis of material left at the scene of a crime.
48. The Crisis Check Database is available
to vulnerable members of society, such as senior executives and
their families, who are at risk of abduction and the identity
of whom may have to be established from samples provided.
Q2B. How are these activities funded?
49. FSS casework activities are funded by
charging the police on a case by case basis for the services provided.
50. Non-police customers are charged directly
for any services provided.
51. FSS research projects are funded in
part by the FSS and in part by the Home Office Science and Technology
Unit.
Q2C. What practical considerations will constrain
developments?
52. Funding; police policy; legislation;
the availability of samples for R&D; the availability of robust
and reliable new equipment/technology and competent staff resources.
Q2D. Are there alternative ways of fulfilling
the objectives?
53. A minor part of FSS research work can
be and is carried out using information databases/databanks openly
available to the scientific community (eg GenBank) and data mining
and manipulation packages (eg FASTA) for searching for and aligning
DAN sequence data. However, genetic information databases from
known and traceable samples are essential for population studies
and the validation of new techniques. These could be produced
on a sub-contract basis as well as in-house.
Q3A. What is the genetic information that
is being collected?
54. Police and Staff Elimination Databases:
STR (SGM Plus) DNA profiles compatible with those on the National
DNA Database.
55. The HLA DQa allelic frequency
database: six alleles at the Human Leucocyte Antigen locus.
56. STR DNA allelic frequency databases:
there are four of these, each with separate sub-sets for the Afro-Caribbean,
Asian and Caucasian populations. The Quad database is based on
four loci: HUMVWFA/31A; HUMF13A; HUMFES. The SGM database is based
on six loci: HUMTHO1; D21S11; D18S51; D8S1179; HUMVWFA/31A and
HUMFIBRA(FGA). The TGM database is based on seven loci: D3S1358;
D1S518; D14S306; HUMTHO1; D10S516; D2S1338 and D22S684. The SGM
Plus database is based on 10 loci: the SGM Plus loci: SGM loci
+ D19S433; D16S539; D2S1338 and D3S1358. As far as we are aware,
none of these STRs code for identifiable gene products or physical
characteristics.
57. Mitochondrial DNA databases: 780 bases
from the mitochondrial DNA control region for the "full sequencing"
service or 13 individual bases from 12 sites of the mitochondrial
DNA control region for the "mini sequencing" service;
none of these is known to code for proteins for RNA.
58. Red hair prediction database: polymorphisms
of the MRSH gene, mutations in which are believed to result in
the red hair phenotype.
59. Crisis Check database: the STR (SGM
Plus) DNA loci.
60. SLP frequency databases, with separate
sub-sets for the Afro-Caribbean, Asian and Caucasian populations:
restriction fragment length polymorphisms of DNA from various
chromosomes obtained using single locus probes: YNH2/chromosome
2; pMLJ14/chromosome 14; g3/chromosome 7; MS1/chromosome 1; MS8/chromosome
5; MS31/chromosome 7; MS43A/chromosome 12; TBQ7/chromosome 10.
Q3B. How is it being stored and protected?
61. The elimination databases contain details
of the genetic information and the identity of the individual
from whom it was derived. The police elimination database is held
by the Custodian of the NDNADB entirely separate and distinct
from the NDNADB, access is restricted and password controlled,
and there are strict rules on how and when it should be used.
The staff elimination database is held by the FSS on a stand alone
computer with restricted password controlled access, and again
there are strict rules on how and when it should be used.
62. The DNA frequency databases and the
mitochondrial DNA population databases contain only the genetic
information; the identity of the person from whom this was derived
is only traceable via separate data sheets not available to users
of the databases.
63. The Red Hair Prediction Database contains
details of the genetic information and the identity of the individual
from whom it was derived. But it was only used to validate the
test and is not now accessed for any purpose.
64. The Crisis Check Database contains only
the genetic information; the identity of the person from whom
this was derived is known only to the customer.
Q4. How do the organisations involved see
their responsibility regarding privacy; consent; future use; public
accountability and intellectual property rights?
65. All donors to the FSS databases are
volunteers who have agreed to the use of their samples and the
data derived from them for specified purposes only. Consent forms
have been used since 1996.
66. IPR is sought by the FSS for procedures
(eg the red hair prediction test) rather than genetic information.
Any published data is written so that genetic information cannot
be traced to an individual.
Q5A. How do they see their activities in the
area of genetic databases developing in the future?
67. Genetic databasing will become quicker
and faster. The use and size of databases will thus increase in
the FSS. The introduction of miniaturised hybridisation assays
would potentially allow a huge increase in data handling.
Q5B. What advances in sequencing, screening
and database technology are they anticipating?
68. See 26.
Q6. What lessons should be learnt from genetic
database initiatives in other countries?
69. The FSS is ahead of other countries
in the use of genetic databases in support of criminal investigations
and we provide support to a number of countries to assist them
in the development of their own systems.
