Genes affected

CAVIN4 (HGNC:33742): (caveolae associated protein 4) This gene encodes a protein containing two coiled-coil regions. The encoded protein promotes Rho/ROCK (Rho-kinase) signaling in cardiac muscles cells, and may facilitate myofibrillar organization. [provided by RefSeq, Jun 2013]

The p.Glu56Asp variant in CAVIN4 (previously known as MURC) has not been previously reported in individuals with cardiomyopathy but has been identified in 0.0009% (1/113566) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of this variant is uncertain.
