Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PVS1PS3PP5

The NM_006231.4(POLE):​c.3264_3275+13delTGTCACGGAGAGGTGAGGGCTCCCC​(p.Val1089_Arg1092del) variant causes a splice donor, disruptive inframe deletion, splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,610,294 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV000653191: Studies have shown that this variant results in activation of a cryptic splice site, and produces a non-functional protein and/or introduces a premature termination codon (internal data).". Synonymous variant affecting the same amino acid position (i.e. P1088P) 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: Pathogenic. The variant received 13 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 8.4, offset of 26, new splice context is: gagGTgagg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PS3
PS3 evidence extracted from ClinVar submissions: SCV000653191: Studies have shown that this variant results in activation of a cryptic splice site, and produces a non-functional protein and/or introduces a premature termination codon (internal data).
PP5
Variant 12-132659281-GGGGGAGCCCTCACCTCTCCGTGACA-G is Pathogenic according to our data. Variant chr12-132659281-GGGGGAGCCCTCACCTCTCCGTGACA-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 473580.
