Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS1

The NM_006231.4(POLE):c.6445C>T(p.Arg2149Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000657 in 1,613,790 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict 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. R2149H) 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: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.10631788).

BP6

Variant 12-132626203-G-A is Benign according to our data. Variant chr12-132626203-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 405704.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000671 (98/1461464) while in subpopulation SAS AF = 0.000441 (38/86244). AF 95% confidence interval is 0.00033. There are 0 homozygotes in GnomAdExome4. There are 56 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
