Collection Method:clinical testing

The c.1807C>T (p.R603W) alteration is located in exon 15 (coding exon 12) of the SCMH1 gene. This alteration results from a C to T substitution at nucleotide position 1807, causing the arginine (R) at amino acid position 603 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
