Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PP2PP3_StrongPP5_Moderate
The ENST00000355349.4(MYH7):c.1159C>T(p.Leu387Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L387V) has been classified as Uncertain significance.

Hypertrophic cardiomyopathy Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Mar 23, 2023 | This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 387 of the MYH7 protein (p.Leu387Phe). For these reasons, this variant has been classified as Pathogenic. 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 expected to disrupt MYH7 protein function. ClinVar contains an entry for this variant (Variation ID: 524975). This missense change has been observed in individual(s) with left ventricular noncompaction (PMID: 31147515; Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). - |
