Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_001146312.3(MYOCD):c.2689G>C(p.Asp897His) variant causes a missense change. The variant allele was found at a frequency of 0.00000898 in 1,446,984 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D897E) has been classified as Likely benign.

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.2689G>C (p.D897H) alteration is located in exon 14 (coding exon 14) of the MYOCD gene. This alteration results from a G to C substitution at nucleotide position 2689, causing the aspartic acid (D) at amino acid position 897 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
