}}Located in the 3' UTR of the [[SKA2]] gene, [[rs7208505]] is reported in a small study to be partially associated with tendencies towards [[suicide]]. In most ethnic groups, the more common allele - in dbSNP orientation - is [[rs7208505]](A), and the less common is [[rs7208505]](G). This latter, less common allele leads to the existence (on both strands) of a CpG dinucleotide capable of being methylated. 

In what is termed an additive genetic and epigenetic association, postmortem analysis of a relatively small number of brains indicates that while carrying the [[rs7208505]](G) allele is not on it's own linked to higher [[suicide]] risk, harboring the methylated dinucleotide containing this allele may be, especially in the presence of a higher waking levels of a marker for increased risk, [[cortisol]].{{PMID|25073599}}

The authors also distinguish between at least three categories of suicide risk: suicide ideation (thinking about it), suicide attempts, and last, death from suicide. The study sample number was too low to sort out all the variables in relation to these categories.
