The c.721A>G (p.S241G) alteration is located in exon 5 (coding exon 4) of the GLTSCR1L gene. This alteration results from a A to G substitution at nucleotide position 721, causing the serine (S) at amino acid position 241 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
