Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PP2PP3_StrongPP5_Moderate
The NM_000257.4(MYH7):c.1426C>T(p.Leu476Phe) variant causes a missense change. 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 Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L476V) has been classified as Uncertain significance.

Hypertrophic cardiomyopathy 1 Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | 3billion | Jan 03, 2022 | Same nucleotide change resulting in same amino acid change has been previously reported to be associated with MYH7 related disorder (PMID:32380161, PS1_P). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.826, 3CNET: 0.953, PP3_P). It is not observed in the gnomAD v2.1.1 dataset (PM2_M). The variant is located in a well-established functional domain or exonic hotspot, where pathogenic variants have frequently reported (PM1_M).Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. - |
