The c.724A>G (p.I242V) alteration is located in exon 3 (coding exon 3) of the EPHA6 gene. This alteration results from a A to G substitution at nucleotide position 724, causing the isoleucine (I) at amino acid position 242 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
