The c.181C>G (p.P61A) alteration is located in exon 1 (coding exon 1) of the PDZRN4 gene. This alteration results from a C to G substitution at nucleotide position 181, causing the proline (P) at amino acid position 61 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
