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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.33).
BP6
Variant 12-132681189-C-T is Benign according to our data. Variant chr12-132681189-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 413585.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=1.52 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000103 (15/1461886) while in subpopulation AFR AF = 0.000388 (13/33480). AF 95% confidence interval is 0.00023. There are 0 homozygotes in GnomAdExome4. There are 9 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
