The c.176C>G (p.P59R) alteration is located in exon 2 (coding exon 2) of the CWH43 gene. This alteration results from a C to G substitution at nucleotide position 176, causing the proline (P) at amino acid position 59 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
