The c.917C>G (p.P306R) alteration is located in exon 9 (coding exon 6) of the SCMH1 gene. This alteration results from a C to G substitution at nucleotide position 917, causing the proline (P) at amino acid position 306 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
