The c.4958A>G (p.E1653G) alteration is located in exon 39 (coding exon 39) of the MYO5C gene. This alteration results from a A to G substitution at nucleotide position 4958, causing the glutamic acid (E) at amino acid position 1653 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
