NM_006231.4:c.6539C>T

Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_006231.4(POLE):​c.6539C>T​(p.Ala2180Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000838 in 1,610,774 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. A2180T) has been classified as Likely benign.

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 -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.012607247).
BP6
Variant 12-132625763-G-A is Benign according to our data. Variant chr12-132625763-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 246197.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000788 (12/152324) while in subpopulation SAS AF = 0.00145 (7/4830). AF 95% confidence interval is 0.000679. There are 0 homozygotes in GnomAd4. There are 7 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
