DNA Commission


The DNA Commission was brought to life in 1987 due to the rapid progress in the development of DNA polymorphisms, and has published its first recommendation in 1989 (Forensic Sci. Int. 43, 109-111). The role of the commission was described in the introduction of this first publication as follows:
 
"­ to discuss these exciting developments in relation to their use in the medico-legal context and (to make) recommendations ­"
 
The DNA Commission is usually represented by the Executive Committee of the ISFG as well as number of experts, who are called into the commission depending on the subject of discussion. The commission has a chairman who is appointed by the Executive Committee, and who is responsible for chairing the meetings, and drafting the recommendations.
 

The DNA commission is chaired by

The recommendations of the DNA Commission have all been published in scientific journals.

There is considerable interest in statistical reporting of the ‘meaning’ of the DNA profile with respect to ‘how’, ‘why’ or ‘when’ did it become evidence. This question is particularly relevant to low level DNA where there is considerable ambiguity about the origin of the DNA sample and its association (if any) with a body fluid. Bayes nets are used as an example of how to report DNA profiles. The commission has examined the ‘state of the science’ to date and provide recommendations on a way forward, along with describing remaining challenges and the likely limitations that exist.

2021: DNA Commission on STR Sequence Nomenclature Requirements
 
The commission will develop a proposal for sequence-based STR nomenclature from massively parallel sequencing efforts, following a meeting of STRAND working group; see Gettings KB, Ballard D, Bodner M, Borsuk LA, King JL, Parson W, Phillips C.
