Variant summary
Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP4_StrongBP6_Very_StrongBS2
The NM_003803.4(MYOM1):c.590C>T(p.Thr197Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00138 in 1,612,030 control chromosomes in the GnomAD database, including 33 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict 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. T197T) has been classified as Likely benign.

Submissions by phenotype
not specified Benign:2
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. -
p.Thr197Met in exon 4 of MYOM1: This variant is not expected to have clinical si gnificance because it has been identified in 1.3% (215/16512) of South Asian chr omosomes, including 4 homozygotes, by the Exome Aggregation Consortium (ExAC, ht tp://exac.broadinstitute.org; dbSNP rs142735495). -
