Genes affected

PTBP3 (HGNC:10253): (polypyrimidine tract binding protein 3) The protein encoded by this gene binds RNA and is a regulator of cell differentiation. The encoded protein preferentially binds to poly(G) and poly(U) sequences in vitro. Several transcript variants encoding different isoforms have been found for this gene.

The c.518A>G (p.N173S) alteration is located in exon 1 (coding exon 1) of the PTBP3 gene. This alteration results from a A to G substitution at nucleotide position 518, causing the asparagine (N) at amino acid position 173 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
