Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1630C>T (p.R544C) alteration is located in exon 13 (coding exon 10) of the SCMH1 gene. This alteration results from a C to T substitution at nucleotide position 1630, causing the arginine (R) at amino acid position 544 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
