Genes affected

MYOCD (HGNC:16067): (myocardin) This gene encodes a nuclear protein, which is expressed in heart, aorta, and in smooth muscle cell-containing tissues. It functions as a transcriptional co-activator of serum response factor (SRF) and modulates expression of cardiac and smooth muscle-specific SRF-target genes, and thus may play a crucial role in cardiogenesis and differentiation of the smooth muscle cell lineage. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

Ambry Genetics

Mar 06, 2023

The c.82A>G (p.R28G) alteration is located in exon 2 (coding exon 2) of the MYOCD gene. This alteration results from a A to G substitution at nucleotide position 82, causing the arginine (R) at amino acid position 28 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
