The c.311C>G (p.P104R) alteration is located in exon 7 (coding exon 1) of the SGMS1 gene. This alteration results from a C to G substitution at nucleotide position 311, causing the proline (P) at amino acid position 104 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
