Description

Variant classified as Uncertain Significance - Favor Benign. The Gln149His varia nt in MYOZ2 has been identified in 1 individual with DCM (LMM unpublished data) and has also been identified in 1/1316 European chromosomes by the ClinSeq proje ct (dbSNP rs200077093). Computational analyses (biochemical amino acid propertie s, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support f or or against an impact to the protein, though 2 fish species carry a histidine (His; this variant) at this position, raising the possibility that it may be tol erated. However, additional studies are needed to fully assess its clinical sign ificance.
