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]

May 25, 2023

The c.2614G>C (p.E872Q) alteration is located in exon 24 (coding exon 24) of the POLN gene. This alteration results from a G to C substitution at nucleotide position 2614, causing the glutamic acid (E) at amino acid position 872 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
