Genes affected

MYPN (HGNC:23246): (myopalladin) Striated muscle in vertebrates comprises large proteins which must be organized properly to contract efficiently. Z-lines in striated muscle are a sign of this organization, representing the ends of actin thin filaments, titin, nebulin or nebulette and accessory proteins required for structure and function. This gene encodes a protein which interacts with nebulin in skeletal muscle or nebulette in cardiac muscle and alpha-actinin. In addition, this gene product can interact with a protein with the I-band indicating it has a regulatory as well as structural function. Alternative splicing results in multiple transcript variants.

The p.Val1195Met variant in MYPN has been reported in at least 2 individuals wit h DCM (Duboscq-Bidot 2008, LMM data). It has been reported in ClinVar (Variant I D: 31792) with conflicting interpretations. This variant has also been identifie d in 0.2% (53/24012) of African chromosomes by the Genome Aggregation Database ( gnomAD, http://gnomad.broadinstitute.org; dbSNP rs71534280). Computational predi ction tools and conservation analysis suggest that this variant may impact the p rotein, though this information is not predictive enough to determine pathogenic ity. A single in vitro functional study reports that the p.Val1195Met variant ma y impact protein function (Duboscq-Bidot 2008). However, these types of assays m ay not accurately represent biological function. In summary, the clinical signif icance of the p.Val1195Met variant is uncertain. -

Ambry Genetics

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -
