Genes affected

MYO5A (HGNC:7602): (myosin VA) This gene is one of three myosin V heavy-chain genes, belonging to the myosin gene superfamily. Myosin V is a class of actin-based motor proteins involved in cytoplasmic vesicle transport and anchorage, spindle-pole alignment and mRNA translocation. The protein encoded by this gene is abundant in melanocytes and nerve cells. Mutations in this gene cause Griscelli syndrome type-1 (GS1) and neuroectodermal melanolysosomal disease, or Elejalde disease. [provided by RefSeq, Sep 2023]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.182 is higher than 0.05.
