Genes affected

MYF6 (HGNC:7566): (myogenic factor 6) The protein encoded by this gene is a probable basic helix-loop-helix (bHLH) DNA binding protein involved in muscle differentiation. The encoded protein likely acts as a heterodimer with another bHLH protein. Defects in this gene are a cause of autosomal dominant centronuclear myopathy (ADCNM). [provided by RefSeq, May 2010]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 940107). This variant has not been reported in the literature in individuals affected with MYF6-related conditions. This variant is present in population databases (rs776368255, gnomAD 0.0009%). This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 61 of the MYF6 protein (p.His61Gln). -
