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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -16 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.78).
BP6
Variant 12-132626325-G-A is Benign according to our data. Variant chr12-132626325-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 240591.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000548 (80/1461004) while in subpopulation AMR AF = 0.000783 (35/44720). AF 95% confidence interval is 0.000578. There are 0 homozygotes in GnomAdExome4. There are 31 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
