  • 1. Why do the silent mutations matter? By Mehis Pold 1 Why do the silent mutations matter? Why should an NGS pipeline enable splice site analysis? Silent mutations are usually of low or no priority in pipelines interpreting NGS genetic findings because their impact is hard to fathom. Unless such pipelines, however, have a robust, up to date capacity to map variants to exon-intron boundaries, important clues may be missed. I wrote a splice-site analysis tool, a perl-script to be specific, which maps genomic variants to the exon-intron boundaries as provided by CCDS and UCSC table browser. My goal was to elucidate how many entries in the version 67 of COSMIC (the Catalogue of Somatic Mutations in Cancer) annotated as ‘Confirmed somatic variant’ and ‘Substitution - coding silent’ map to the acceptor site ‘+1 position’ (see the below figure, red arrow) because this position can be considered conserved in the U2 intron-exon junctions. I found a total of 124 variant ‘+1’ acceptor positions annotated as ‘Substitution - coding silent’ and ‘Confirmed somatic variant’ in COSMIC (see the below table). Curiously, COSMIC provides no annotations relative to splice sites, and hence, the variants matching the ones in COSMIC should most certainly analyzed in regard to the splice acceptor and donor coordinates. Otherwise, the potentially pathogenic variants can very simply be overlooked.
