The c.1469G>T (p.G490V) alteration is located in exon 13 (coding exon 10) of the SCMH1 gene. This alteration results from a G to T substitution at nucleotide position 1469, causing the glycine (G) at amino acid position 490 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
