The c.4757C>T (p.P1586L) alteration is located in exon 27 (coding exon 27) of the PCNX2 gene. This alteration results from a C to T substitution at nucleotide position 4757, causing the proline (P) at amino acid position 1586 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
