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]

The c.527C>T (p.A176V) alteration is located in exon 6 (coding exon 6) of the MYOCD gene. This alteration results from a C to T substitution at nucleotide position 527, causing the alanine (A) at amino acid position 176 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
