The c.718G>T (p.V240L) alteration is located in exon 9 (coding exon 6) of the SCMH1 gene. This alteration results from a G to T substitution at nucleotide position 718, causing the valine (V) at amino acid position 240 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
