Neuberg Centre For Genomic Medicine, NCGM RCV004720654 SCV005329447 uncertain significance Hypertrophic cardiomyopathy 14 2023-05-20 criteria provided, single submitter clinical testing The missense variant c.2334G>C (p.Met778Ile) in the MYH6 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency (0.0007%) in the gnomAD Exomes and absent in 1000 Genomes. The amino acid Methionine at position 778 is changed to an Isoleucine changing protein sequence and it might alter its composition and physico-chemical properties. Computational evidence (Polyphen, SIFT and MutationTaster) predicts conflicting evidence on protein structure and function for this variant. The amino acid change p.Met778Ile in MYH6 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
