The c.1961G>A (p.R654Q) alteration is located in exon 16 (coding exon 13) of the SCMH1 gene. This alteration results from a G to A substitution at nucleotide position 1961, causing the arginine (R) at amino acid position 654 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
