The c.94G>A (p.G32S) alteration is located in exon 1 (coding exon 1) of the LYSMD2 gene. This alteration results from a G to A substitution at nucleotide position 94, causing the glycine (G) at amino acid position 32 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
