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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.56C>T (p.S19L) alteration is located in exon 1 (coding exon 1) of the MURC gene. This alteration results from a C to T substitution at nucleotide position 56, causing the serine (S) at amino acid position 19 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
