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]

The c.5420G>A (p.R1807H) alteration is located in exon 41 (coding exon 41) of the MYO5A gene. This alteration results from a G to A substitution at nucleotide position 5420, causing the arginine (R) at amino acid position 1807 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
