REVEL	0.46	indeterminate
SaProt	LLR -8.85	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.

Variant & gene context

Gene: BMP10
Protein: p.Arg155Cys
Coding: c.463C>T
MANE Select: NM_014482
Type: single nucleotide variant
Location: chr2:68866443 (GRCh38)
Gene constraint: LOEUF 0.503 · pLI 0.98 (gnomAD)
Structure: AlphaFold pLDDT 74.74 · 8 PDB
Residue 155: a UniProt-annotated variant site (found in a family with congenital heart defects; likely pathogenic; loss of function in bmp signaling pathway; contrary to the wild type, it is unable to stimulate gene expression from tbx20 and nkx2-5 promoters in a luciferase reporter assay)
