Genes affected

POLN (HGNC:18870): (DNA polymerase nu) This gene encodes a DNA polymerase type-A family member. The encoded protein plays a role in DNA repair and homologous recombination. This gene shares its 5' exons with some transcripts from overlapping GeneID: 79441, which encodes an augmentin-like protein complex subunit. [provided by RefSeq, Dec 2014]

ENSG00000290263 (HGNC:):
