Genes affected

PCBP3 (HGNC:8651): (poly(rC) binding protein 3) This gene encodes a member of the KH-domain protein subfamily. Proteins of this subfamily, also referred to as alpha-CPs, bind to RNA with a specificity for C-rich pyrimidine regions. Alpha-CPs play important roles in post-transcriptional activities and have different cellular distributions. The protein encoded by this gene lacks the nuclear localization signals found in other subfamily members. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

The c.631C>T (p.R211C) alteration is located in exon 8 (coding exon 8) of the PCBP3 gene. This alteration results from a C to T substitution at nucleotide position 631, causing the arginine (R) at amino acid position 211 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
