Collection Method: clinical testing

The c.1231G>A (p.V411I) alteration is located in exon 11 (coding exon 8) of the SCMH1 gene. This alteration results from a G to A substitution at nucleotide position 1231, causing the valine (V) at amino acid position 411 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
