The c.457A>G (p.R153G) alteration is located in exon 4 (coding exon 4) of the MYO1H gene. This alteration results from a A to G substitution at nucleotide position 457, causing the arginine (R) at amino acid position 153 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
