The recorded framework is Not recorded. 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.
NM_032043.3:c.254C>T is present at extremely low frequency in population databases: gnomAD v2.1 AF=1.19e-5 (3/251,440 alleles), gnomAD v4.1 AF=9.91e-6 (16/1,613,990 alleles), gnomAD-Canada absent. Both frequencies are well below the 0.1% PM2 threshold for a rare variant in a gene associated with dominant disease.
Multiple lines of computational evidence suggest NM_032043.3:c.254C>T does not impact gene product function. REVEL score is 0.078 (strongly benign-leaning, threshold for pathogenic is >0.5). BayesDel score is -0.316 (negative, indicating benign). SpliceAI max delta is 0.03 (no predicted splicing impact). These concordant predictions from independent algorithms support a benign interpretation.
gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM2 supporting, BP4 supporting benign; combination = 1 supporting + 1 supporting benign, which maps to VUS.

OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. BRIP1, a DEAH helicase, is altered by mutation and amplification in various cancers, including breast cancer and melanoma.
This variant has previously been reported in somatic cancers (COSMIC; COSV113270205, n = 1 times).
This variant does not lie in a statistically significant hotspot.

NM_032043.3:c.254C>T (p.Ser85Leu) is a missense variant in BRIP1. PVS1 does not apply as this is not a null variant.
This variant is present at extremely low frequency in population databases: gnomAD v2.1 at 0.00119% (3/251,440 alleles) and gnomAD v4.1 at 0.00099% (16/1,613,990 alleles), with no homozygotes observed. This meets the PM2 criterion at supporting strength for a rare variant in a gene associated with dominant cancer predisposition.
Multiple in silico prediction tools support a benign effect: REVEL score 0.078 (strongly benign-leaning), BayesDel score -0.316 (benign), and SpliceAI max delta 0.03 (no predicted splicing impact). These concordant predictions meet BP4 at supporting benign strength.
No functional studies have directly tested p.Ser85Leu. The largest BRIP1 missense functional characterization study (PMID:31822495) tested 20 helicase domain variants but did not include this residue. OncoKB reports no variant-specific functional evidence.
ClinVar classifies this variant as Uncertain Significance (Variation ID: 141545) with 1-star review status based on 14 clinical laboratory submissions. No expert panel classification is available. This does not meet criteria for PP5 or BP6 application.
No case-control studies, cosegregation data, de novo reports, or same-residue pathogenic comparators are available. BRIP1 missense variants in the helicase domain are a known disease mechanism (PMID:31822495), so BP1 does not apply despite this being a missense change.
The combined evidence (PM2 supporting + BP4 supporting benign) yields conflicting benign and pathogenic signals. The overall classification is Variant of Uncertain Significance (VUS), consistent with the ClinVar consensus.
