Description

The POLE p.Tyr1395Cys variant was not identified in the literature. The variant was identified in dbSNP (ID: rs5744933) as "With other allele" and in ClinVar (classified as benign by Invitae and Prevention Genetics; as likely benign by GeneDx; and as uncertain significance by one submitter). The variant was identified in control databases in 206 of 277082 chromosomes (1 homozygous) at a frequency of 0.0007 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 189 of 24032 chromosomes (1 homozygous; freq: 0.008, increasing the likelihood this could be a low frequency benign variant), Other in 1 of 6466 chromosomes (freq: 0.0002), Latino in 15 of 34408 chromosomes (freq: 0.0004), European in 1 of 126596 chromosomes (freq: 0.000008), while the variant was not observed in the Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.Tyr1395 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.
