Classification rationale
1

The BRIP1 c.1171A>G (p.Ile391Val) variant has been reported in ClinVar and is currently classified there as a variant of uncertain significance with single-submitter review status.

OncoKB: Unknown Oncogenic Effect
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.
