The c.418C>G (p.H140D) alteration is located in exon 2 (coding exon 2) of the CMYA5 gene. This alteration results from a C to G substitution at nucleotide position 418, causing the histidine (H) at amino acid position 140 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
