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.
This variant is present at extremely low allele frequency in population databases: gnomAD v2.1 AF = 4.10e-06 (1/244,126 alleles, 0 homozygotes) and gnomAD v4.1 AF = 6.20e-07 (1/1,611,808 alleles, 0 homozygotes). Both frequencies are well below the 0.1% PM2 threshold. The variant is absent from gnomAD-Canada v1.0.
SpliceAI predicts no significant splice impact for this intronic substitution (max delta score = 0.01), suggesting the variant is unlikely to disrupt normal splicing of POLE. The custom León-Castillo BP4 rule applies only to missense variants in Supplementary Tables S2/S3 and is not triggered here; under generic BP4 assessment, computational evidence supports a neutral effect.
This variant has been classified as Likely benign by a clinical diagnostic laboratory (Labcorp Genetics, formerly Invitae; ClinVar SCV004525736, VariationID 2897960) with criteria provided. The submitter is a reputable clinical testing laboratory.
The custom León-Castillo et al. 2020 POLE framework was used as the primary classification framework. Only supporting-strength criteria are met: one pathogenic (PM2_Supporting) and two benign (BP4_Supporting, BP6_Supporting). Under the framework's likely_benign combination rules, >=2 Supporting benign criteria are sufficient for a Likely Benign classification.

NM_006231.4:c.1474-9C>T is an intronic substitution in POLE located 9 bases upstream of exon 14. SpliceAI predicts no significant splicing impact (max delta score = 0.01), indicating the variant is unlikely to alter normal splicing.
This variant is extremely rare in population databases, with an allele frequency of 4.10e-06 in gnomAD v2.1 (1/244,126 alleles) and 6.20e-07 in gnomAD v4.1 (1/1,611,808 alleles), both meeting the PM2_Supporting threshold for absence from population databases.
ClinVar classifies this variant as Likely benign (VariationID 2897960, Labcorp Genetics, criteria provided, single submitter), supporting benign interpretation under BP6_Supporting.
SpliceAI predicts no significant splice impact (max delta score = 0.01), consistent with a neutral computational assessment under BP4_Supporting.
No pathogenic evidence criteria are met. The custom León-Castillo PM1 and PS4 rules are missense-specific and do not apply to this intronic substitution. The variant is absent from COSMIC and the León-Castillo supplementary tables. No de novo observations, functional studies, or segregation data are available.
Applying the custom León-Castillo framework with generic ACMG/AMP 2015 fallback: the variant accrues one pathogenic supporting criterion (PM2_Supporting) and two benign supporting criteria (BP4_Supporting, BP6_Supporting). Under the likely_benign combination rules of the framework, two supporting benign criteria are sufficient for a classification of Likely benign. This classification is consistent with the existing ClinVar classification.
