The c.379G>A (p.G127S) alteration is located in exon 5 (coding exon 5) of the AFMID gene. This alteration results from a G to A substitution at nucleotide position 379, causing the glycine (G) at amino acid position 127 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
