Description

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 123 of the ANKRD1 protein (p.Thr123Met). This variant is present in population databases (rs145387010, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 19608031, 31737537). ClinVar contains an entry for this variant (Variation ID: 191577). 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 ANKRD1 protein function with a negative predictive value of 80%. 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.
