ZFYVE9
Chr 1zinc finger FYVE-type containing 9
Also known as: MADHIP, NSP, PPP1R173, SARA, SMADIP
This gene encodes an early endosomal protein that recruits SMAD2 and SMAD3 to intracellular membranes and the TGF-beta receptor, regulating their subcellular localization and modulating SMAD3/SMAD4 transcriptional activity in TGF-beta signaling pathways. The gene is highly constrained against loss-of-function variants (pLI 0.90, LOEUF 0.33), suggesting mutations likely cause autosomal dominant disease, though specific associated phenotypes are not yet established in clinical databases.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Mild missense constraint
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
