rs147562871

Description

This sequence change replaces tyrosine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 600 of the MUSK protein (p.Tyr600Asn). This variant is present in population databases (rs147562871, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with MUSK-related conditions. ClinVar contains an entry for this variant (Variation ID: 844158). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MUSK protein function. 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.
