About BRIP1

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.
01The reasoning

How it was classified

The recorded framework is Not recorded. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

Recorded applied criteria

The applied criteria and their strengths are shown as assessed under the stated framework.

Pathogenic evidence criteria: 1 Benign evidence criteria: 1
Pathogenic criteria applied · 1
PM2Moderate
PM2 · moderate

This variant is present at low frequency in population databases. The highest observed population frequency is 0.06533% in gnomAD v2.1 South Asian samples and 0.04721% in gnomAD v4.1 South Asian samples, both below the default 0.1% PM2 threshold, which supports PM2 under the generic fallback framework.

Benign criteria applied · 1
BP7Supporting
BP7 · supporting

This is a synonymous BRIP1 variant, p.(Leu1023=), and available splicing prediction does not indicate a meaningful splice effect. SpliceAI shows a maximum delta score of 0.01, supporting no significant splice impact, which meets BP7.

Recorded classification: Uncertain significance

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 moderate, BP7 supporting benign; combination = 1 moderate, which maps to VUS because the evidence is conflicting.

Met Not met Not assessed Not applicable

The BRIP1 c.3069C>T (p.Leu1023=, p.L1023=) variant has been reported in ClinVar predominantly as likely benign or benign.

This variant is present at low frequency in gnomAD, with overall allele frequencies of 0.01061% in v2.1 and 0.00836% in v4.1, and highest observed South Asian frequencies of 0.06533% and 0.04721%, respectively; these values are below the default 0.1% PM2 threshold and below the 0.3% BS1 and 1% BA1 benign thresholds.

This synonymous variant is predicted to have no significant splice effect, with a SpliceAI maximum delta score of 0.01, which supports BP7 and argues against PP3.
