The variant received -2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_ModerateB4_Strong

The NM_032043.3(BRIP1):c.1200C>T (p.Asp400Asp) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The gene BRIP1 is a tumor suppressor gene (CancerMine: 11 TSG, 4 oncogene, 1 driver citations). The gene BRIP1 is a known oncogene (CancerMine: 11 TSG, 4 oncogene, 1 driver citations). The gene BRIP1 is a cancer driver gene (CancerMine: 11 TSG, 4 oncogene, 1 driver citations). The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★). The variant has been observed in cBioPortal in 1 sample across 1 study and 1 cancer type; somatic enrichment level: NONE (Observed in at most one deduplicated cBioPortal case.).

Genes affected

BRIP1 (HGNC:20473): (BRCA1 interacting DNA helicase 1) The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations.

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -2 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Absent or extremely rare in gnomAD (AC ≤ 2) — O3 moderate; GnomAD: AF = absent, AC = 0 — absent/extremely rare (O3 moderate [+2])
	B4Synonymous/intronic, no splicing impact		Synonymous/intronic variant with confirmed no splicing impact (B4 strong); Synonymous variant — splicing algorithms confirm no impact on splicing (B4 strong [-4])
