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]

Ambry Genetics

Dec 14, 2021

The c.1889G>A (p.R630H) alteration is located in exon 17 (coding exon 17) of the POLN gene. This alteration results from a G to A substitution at nucleotide position 1889, causing the arginine (R) at amino acid position 630 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
