Mutations in KCNA5 have the potential to affect the onset and severity of the disease process (PMID: 25189502,19223935, 17641158, 26167679).Variation of the potassium channel KCNA5 was initially dentified in IPAH patients PMID:17267549 (2007), 25189502 (2014) suggesting a potential role in PAH development and penetrance, in that KCNA5 is a potential predisposition modulator to PAH. In PMID: 25189502 mutations within KCNA5 were identified as a ‘second hit’ in an index patient additional to a BMPR2 missense mutation leading to an early onset and severe phenotype, representing a rare case of genetic modification in PAH. In PMID: 27630060 (2016) genotype-phenotype correlation was performed on Fifty-seven PAH patients (28 idiopathic PAH, 29 associated PAH group I). Several mutations in different genes, classified as pathogenic by in silico analysis, were present in 26% of PAH patients. The most commonly involved gene was BMPR2 (12 patients) followed by ENG gene (9 patients). ACVRL1 and KCNA5 genes showed very low incidence of mutations (5 and 1 patients, respectively).

Panel reviews were assessed, and panel was revised according to reviews and further in-house curation.
