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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.787A>G (p.S263G) 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 787, causing the serine (S) at amino acid position 263 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
