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

Our verdict: Likely_benign. The variant received -1 ACMG points.

• BS1: Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000092 (14/152152) while in subpopulation AMR AF = 0.000851 (13/15274). AF 95% confidence interval is 0.000503. There are 0 homozygotes in GnomAd4. There are 10 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
