Why a Database?

Why a stored set of genetic profiles matters for missing and unidentified persons.

What is a database?

According to the oxford dictionary a database is defined as ‘a structured set of data held in a computer, especially one that is accessible in various ways’ and we at AIIMS, New Delhi intend to create a DNA database of unidentified bodies to aid in forensic INVESTIGATIONS OF MISSING AND UNIDENTIFIED BODIES. A DNA database is a stored set of genetic profiles that has its uses in identification of missing persons.

DNA databases around the world

The United Kingdom established a national DNA database (NDNAD) for the first time in 1995 and used it for the purpose of solving crimes. As of 2018, there are 56 forensic DNA databases found worldwide. China currently has the largest DNA database followed by USA (CODIS), United Kingdom and France. Included in this database is also a DNA database of missing persons and unidentified human remains. A global DNA profiling survey is conducted by INTERPOL every two years in which INTERPOL asks countries to deliver their national DNA statistics. Using this they examine the use of DNA databases and DNA profiling in several countries. The graphs show the number of DNA profiles of unidentified human remains and missing persons maintained in the database of some countries along with reference DNA profiles which are used for matching, as per the Global DNA Profiling Survey of 2016.

Public access and coordination

The UMID database provides public access to family members and authorities who wish to search for missing persons and claim an unidentified body. Further, this database would also be helpful to maintain a coordination between different investigation agencies over the country and would add another parameter to ongoing investigations.
