The c.643T>C (p.C215R) alteration is located in exon 3 (coding exon 3) of the EPHA6 gene. This alteration results from a T to C substitution at nucleotide position 643, causing the cysteine (C) at amino acid position 215 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
