The recorded framework is León-Castillo et al. 2020 custom POLE framework. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
The allele frequency of NM_006231.4:c.1360-6C>T in the African/African American subpopulation exceeds the 0.3% BS1 threshold for non-VCEP assessment: 0.324% in gnomAD v2.1 (81/24,970 alleles) and 0.353% in gnomAD v4.1 (262/74,194 alleles, including 2 homozygotes). The gnomAD v4.1 grpmax FAF is 0.318% (>0.3%). This frequency is greater than expected for a pathogenic variant in a rare cancer predisposition gene.
Three homozygous individuals for NM_006231.4:c.1360-6C>T are observed in gnomAD v4.1 (exome data: 2 in the African/African American subpopulation, 1 in the South Asian subpopulation). For a gene where pathogenic germline variants are associated with a rare autosomal dominant cancer predisposition syndrome (POLE-associated polyposis and colorectal cancer), the observation of homozygous individuals in a population database is inconsistent with a pathogenic role.
The León-Castillo et al. 2020 custom POLE framework (local gene-specific) was used. Two supporting benign criteria (BS1 and BS2) are met, satisfying the '>=2 Supporting benign' rule for Likely Benign. No pathogenic criteria are met.

NM_006231.4:c.1360-6C>T is present in gnomAD v4.1 at an allele frequency of 0.0239% overall (376/1,574,938 alleles) and 0.353% in the African/African American subpopulation (262/74,194 alleles), exceeding the 0.3% threshold for BS1 at supporting benign strength.
Three homozygous individuals for c.1360-6C>T are observed in gnomAD v4.1 (2 African/African American, 1 South Asian), which is inconsistent with a pathogenic role in an autosomal dominant cancer predisposition syndrome, satisfying BS2 at supporting benign strength.
SpliceAI predicts no significant splice impact for this intronic variant (max delta score = 0.15, below the 0.2 threshold). The variant does not disrupt the canonical splice consensus sequence.
This variant has been reported in ClinVar as Likely benign by 8 clinical laboratories and Benign by 5 clinical laboratories (ClinVar ID 240389), with concordance across 13 clinical submitters, consistent with a benign interpretation.
No pathogenic ACMG/AMP criteria are met. Two supporting benign criteria (BS1 and BS2) are met, satisfying the >=2 supporting benign rule for a Likely Benign classification per the ACMG/AMP 2015 framework with custom POLE specifications.
