Genes affected

MEF2A (HGNC:6993): (myocyte enhancer factor 2A) The protein encoded by this gene is a DNA-binding transcription factor that activates many muscle-specific, growth factor-induced, and stress-induced genes. The encoded protein can act as a homodimer or as a heterodimer and is involved in several cellular processes, including muscle development, neuronal differentiation, cell growth control, and apoptosis. Defects in this gene could be a cause of autosomal dominant coronary artery disease 1 with myocardial infarction (ADCAD1). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.05635968).
• BP6: Variant 15-99690352-A-G is Benign according to our data. Variant chr15-99690352-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 8950.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High AC in GnomAd at 143 AD gene.
