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 -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BP6: Variant 15-52313693-C-G is Benign according to our data. Variant chr15-52313693-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 435920.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000407 (62/152262) while in subpopulation EAS AF= 0.00636 (33/5188). AF 95% confidence interval is 0.00465. There are 2 homozygotes in gnomad4. There are 34 alleles in male gnomad4 subpopulation. This position pass quality control queck.
