The c.3955C>T (p.R1319C) alteration is located in exon 20 (coding exon 20) of the PXDNL gene. This alteration results from a C to T substitution at nucleotide position 3955, causing the arginine (R) at amino acid position 1319 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
