Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM1BP4_ModerateBS1_Supporting

The NM_006231.4(POLE):​c.4169G>A​(p.Arg1390His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000117 in 1,613,342 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1390C) has been classified as Uncertain significance.

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: Likely_benign. The variant received -1 ACMG points.

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 6 benign, 40 uncertain in NM_006231.4
BP4
Computational evidence support a benign effect (MetaRNN=0.14608943).
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000118 (172/1461110) while in subpopulation MID AF = 0.000867 (5/5766). AF 95% confidence interval is 0.000341. There are 0 homozygotes in GnomAdExome4. There are 81 alleles in the male GnomAdExome4 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
