Genes affected

POLDIP3 (HGNC:23782): (DNA polymerase delta interacting protein 3) This gene encodes an RRM (RNA recognition motif)-containing protein that participates in the regulation of translation by recruiting ribosomal protein S6 kinase beta-1 to mRNAs. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

The c.682A>G (p.T228A) alteration is located in exon 5 (coding exon 5) of the POLDIP3 gene. This alteration results from a A to G substitution at nucleotide position 682, causing the threonine (T) at amino acid position 228 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
