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=-0.69).

BP6

Variant 12-132676609-G-A is Benign according to our data. Variant chr12-132676609-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 240632.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-0.022 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00273 (415/152230) while in subpopulation AFR AF = 0.00956 (397/41538). AF 95% confidence interval is 0.00878. There are 2 homozygotes in GnomAd4. There are 196 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR,AD gene
