Protein change
AlphaMissense	0.1697	likely benign
REVEL	0.261	benign-leaning
SaProt	LLR -7.47	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.Asn90Asp
Coding: c.268A>G
MANE Select: NM_014482
dbSNP: rs2103812921
Type: single nucleotide variant
Location: chr2:68871091 (GRCh38)
Gene constraint: LOEUF 0.503 · pLI 0.98 (gnomAD)
Structure: AlphaFold pLDDT 74.74 · 8 PDB
Residue 90: an α-helix; 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)
