The c.732C>G (p.C244W) alteration is located in exon 1 (coding exon 1) of the MEPCE gene. This alteration results from a C to G substitution at nucleotide position 732, causing the cysteine (C) at amino acid position 244 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
