The c.356G>C (p.G119A) alteration is located in exon 3 (coding exon 1) of the MROH7 gene. This alteration results from a G to C substitution at nucleotide position 356, causing the glycine (G) at amino acid position 119 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
