Comment:

This indel at c.1213_1216delinsGCATGT (p.Pro405Alafs*9) was seen on exome through the Texome Project (R01HG011795). It has not been observed in healthy populations (PM2). This stop-gain variant is located in exon 2 of 3 and is predicted to be deleterious (PP3) and results in nonsense mediated decay in a gene where LOF is a documented mechanism of disease (PVS1) (PMID: 11285244). We determine this change to be likely pathogenic.
