A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases. DNA databases are often employed in forensic investigations.
The US government's own Combined DNA Index System (CODIS) database is composed of forensic evidence assessable to local, state, and federal law enforcement officials. This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [26]
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

The CODIS database contains several different indexes for the storage of DNA profile information. For assistance in criminal investigations three indexes exist: the offender index, which contains DNA profiles of those convicted of crimes; the arrestee index, which contains profiles of those arrested of crimes pursuant to the laws of the particular state; and the forensic index, which contains ...
The National Forensic DNA Database of South Africa (NFDD) is a national DNA database used in law enforcement in South Africa.The Criminal Law (Forensic Procedures) Amendment Act No. 37 of 2013 (the "DNA Act") provides for the expansion and administration of such a database in South Africa, enabling the South African Police Service (SAPS) to match forensic DNA profiles derived from samples ...
Familial DNA searching (sometimes referred to as "familial DNA" or "familial DNA database searching") is the practice of creating new investigative leads in cases where DNA evidence found at the scene of a crime (forensic profile) strongly resembles that of an existing DNA profile (offender profile) in a state DNA database but there is not an ...
One study found about 75% of the available DNA in those databases comes from people of northern European descent. "Children of color, families of color, have a smaller footprint in the DNA ...
