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]

Collection Method: clinical testing

The c.88G>A (p.A30T) alteration is located in exon 1 (coding exon 1) of the MURC gene. This alteration results from a G to A substitution at nucleotide position 88, causing the alanine (A) at amino acid position 30 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
