The c.895G>A (p.G299S) alteration is located in exon 3 (coding exon 3) of the MANSC4 gene. This alteration results from a G to A substitution at nucleotide position 895, causing the glycine (G) at amino acid position 299 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
