dbSNP rs530335133: POLN:p.Gly849Cys (chr4-2072272-C-A) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_181808.4(POLN):c.2545G>T(p.Gly849Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000138 in 1,590,172 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G849S) has been classified as Uncertain significance.

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]
