What condition is associated with BRIP1 p.Tyr8Ter (c.24T>A)?

BRIP1 p.Tyr8Ter (c.24T>A) is associated with hereditary breast carcinoma, Fanconi anemia complementation group J, hereditary neoplastic syndrome (ClinVar).

How common is BRIP1 p.Tyr8Ter (c.24T>A) in the general population?

BRIP1 p.Tyr8Ter (c.24T>A) is very rare (popmax 0.000254%, nfe) (gnomAD).

How is Hereditary breast cancer inherited?

Typically Autosomal dominant, Multigenic/multifactorial (Orphanet). A genetic counselor can assess individual risk for a family.

Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.
Consequence	nonsense (stop-gain)	predicted loss-of-function in a haploinsufficient gene (ClinGen)
NMD	predicted	premature termination codon in exon 2 of 20
Splicing
SpliceAI	—	not assessed · no allele here is in the release
Constraint at this position
Conservation	phyloP 3.6	GERP -0.72, phastCons 1
Overall
CADD	35.0	PHRED · no single calibrated threshold — expert panels disagree

Predicted loss-of-function is descriptive, not an applied PVS1 code.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
