The c.245C>G (p.P82R) alteration is located in exon 1 (coding exon 1) of the GSG1L gene. This alteration results from a C to G substitution at nucleotide position 245, causing the proline (P) at amino acid position 82 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
