Variant summary
Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_ModerateBP6_Very_StrongBP7
The NM_000257.4(MYH7):c.1671G>A(p.Leu557=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000125 in 1,614,030 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. L557L) has been classified as Likely benign.

Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 17, 2017 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
