W305S (p.Trp305Ser) variant of KCNQ1 (Potassium voltage-gated channel subfamily KQT member 1)
W305S (p.Trp305Ser) in KCNQ1 (Potassium voltage-gated channel subfamily KQT member 1) is a missense change. Clinical records from ClinVar, EBI, and UniProt describe it as pathogenic/likely pathogenic in the context of Cardiovascular phenotype; not provided; Long QT syndrome. The available variant effect predictions contribute to a CATVariant prioritization score of 0.91 / 1. The record also includes population frequency data, published literature, and structural context.
