The c.73A>G (p.S25G) alteration is located in exon 2 (coding exon 2) of the SPX gene. This alteration results from a A to G substitution at nucleotide position 73, causing the serine (S) at amino acid position 25 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
