Is BAP1 p.Ser395Ter (c.1184C>G) pathogenic?

BAP1 p.Ser395Ter (c.1184C>G) is classified Pathogenic/Likely pathogenic in BAP1 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2024-04-05). Absent from gnomAD v4.1; Associated with BAP1-related tumor predisposition syndrome.

What condition is associated with BAP1 p.Ser395Ter (c.1184C>G)?

BAP1 p.Ser395Ter (c.1184C>G) is associated with BAP1-related tumor predisposition syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BAP1 p.Ser395Ter (c.1184C>G) in the general population?

BAP1 p.Ser395Ter (c.1184C>G) is absent from gnomAD v4.1 (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 12	GERP 1.8, phastCons 1
Overall
CADD	38.0	PHRED · no single calibrated threshold — expert panels disagree

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