Collection Method:clinical testing

The c.13T>C (p.W5R) alteration is located in exon 2 (coding exon 1) of the PNLIPRP1 gene. This alteration results from a T to C substitution at nucleotide position 13, causing the tryptophan (W) at amino acid position 5 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
