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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 13, 2019 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acids is currently unknown. This variant has not been reported in the literature in individuals with POLD1-related disease. This variant is not present in population databases (ExAC no frequency). This variant, c.338_370del, results in the deletion of 11 amino acids of the POLD1 protein (p.Gly113_Pro123del), but otherwise preserves the integrity of the reading frame. - |
