The c.709G>C (p.G237R) alteration is located in exon 1 (coding exon 1) of the MCTP1 gene. This alteration results from a G to C substitution at nucleotide position 709, causing the glycine (G) at amino acid position 237 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
