The c.557C>G (p.P186R) alteration is located in exon 6 (coding exon 6) of the TDRD3 gene. This alteration results from a C to G substitution at nucleotide position 557, causing the proline (P) at amino acid position 186 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
