Genes affected

POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The POLE p.Arg260Gln variant was not identified in the literature nor was it identified in the databases. The variant was identified in dbSNP (ID: rs5744752) as "With Likely benign allele", in ClinVar (classified as benign by Invitae, Prevention Genetics, Quest Diagnostics; as likely benign by GeneDx and Ambry Genetics). The variant was identified in control databases in 289 of 277244 chromosomes (4 homozygous) at a frequency of 0.001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 237 of 24036 chromosomes (freq: 0.0099), Other in 3 of 6468 chromosomes (freq: 0.0005), Latino in 28 of 34420 chromosomes (freq: 0.0008), European Non-Finnish in 18 of 126726 chromosomes (freq: 0.0001), East Asian in 2 of 18868 chromosomes (freq: 0.0001), and South Asian in 1 of 30782 chromosomes (freq: 0.00003); it was not observed in the Ashkenazi Jewish or European Finnish populations. The p.Arg260 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

Benign:2

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Jul 06, 2015	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
