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.625C>T (p.H209Y) alteration is located in exon 4 (coding exon 4) of the POLDIP3 gene. This alteration results from a C to T substitution at nucleotide position 625, causing the histidine (H) at amino acid position 209 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
