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]

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Variant summary: The POLE c.3126G>A (p.Lys1042Lys) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a polymorphism outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 795/121290 control chromosomes (19 homozygotes) at a frequency of 0.0065545, which is approximately 461 times the estimated maximal expected allele frequency of a pathogenic POLE variant (0.0000142), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as benign. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as 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. -

The POLE p.Lys1042= variant was identified in dbSNP (ID: rs5744856) â€šÃ„ÃºWith Benign alleleâ€šÃ„Ã¹. The variant was also identified in control databases in 1996 (73 homozygous) of 277210 chromosomes at a frequency of 0.007, 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 1809 (73 homozygous) of 24028 chromosomes (freq: 0.08), Other in 12 of 6466 chromosomes (freq: 0.002), Latino in 127 of 34420 chromosomes (freq: 0.004), European Non-Finnish in 26 of 126698 chromosomes (freq: 0.0002), Ashkenazi Jewish in 8 of 10152 chromosomes (freq: 0.0008), and South Asian in 14 of 30782 chromosomes (freq: 0.0005), while not observed in the East Asian or European Finnish populations. The p.Lys1042= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence, although 1 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign. -
