Genes affected

POLD1 (HGNC:9175): (DNA polymerase delta 1, catalytic subunit) This gene encodes the 125-kDa catalytic subunit of DNA polymerase delta. DNA polymerase delta possesses both polymerase and 3' to 5' exonuclease activity and plays a critical role in DNA replication and repair. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6. [provided by RefSeq, Mar 2012]

This variant is denoted POLD1 c.2717+11G>A or IVS21+11G>A and consists of a G>A nucleotide substitution at the +11 position of intron 21 of the POLD1 gene. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. POLD1 c.2717+11G>A was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. The guanine (G) nucleotide that is altered is not conserved across species. In silico splicing models are uninformative; therefore, in the absence of RNA or functional studies, the actual effect of this variant is unknown. Based on currently available information, it is unclear whether POLD1 c.2717+11G>A is pathogenic or benign. We consider it to be a variant of uncertain significance. -
