Is BAP1 p.Arg385Ter (c.1153C>T) pathogenic?

BAP1 p.Arg385Ter (c.1153C>T) is classified Pathogenic in BAP1 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2026-01-11). Very rare (popmax 6.84e-05%); Associated with BAP1-related tumor predisposition syndrome.

What condition is associated with BAP1 p.Arg385Ter (c.1153C>T)?

BAP1 p.Arg385Ter (c.1153C>T) is associated with BAP1-related tumor predisposition syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BAP1 p.Arg385Ter (c.1153C>T) in the general population?

BAP1 p.Arg385Ter (c.1153C>T) is very rare (popmax 6.84e-05%) (gnomAD).

How is BAP1-related tumor predisposition syndrome inherited?

Typically Autosomal dominant (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-escape possible for C-terminal truncations
Splicing
SpliceAI	—	not assessed · no allele here is in the release
Constraint at this position
Conservation	phyloP 6.4	GERP 1.8, phastCons 1
Overall
CADD	36.0	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.
