ANKFY1

Chr 17

ankyrin repeat and FYVE domain containing 1

Also known as: ANKHZN, BTBD23, ZFYVE14

This protein regulates endosomal trafficking and fusion, serving as an effector of Rab5 and binding phosphatidylinositol 3-phosphate to control vesicle transport between early endosomes, the Golgi, and lysosomes. Mutations cause autosomal dominant neurodevelopmental disorder with impaired intellectual development, hypotonia, and behavioral abnormalities. The gene is highly constrained against loss-of-function mutations, indicating that ANKFY1 haploinsufficiency is likely not tolerated in the general population.

Clinical SummaryANKFY1
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.96). One damaged copy is likely sufficient to cause disease.
