The c.1027G>A (p.G343S) alteration is located in exon 2 (coding exon 2) of the MEX3A gene. This alteration results from a G to A substitution at nucleotide position 1027, causing the glycine (G) at amino acid position 343 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
