INSYN2A

Chr 10

inhibitory synaptic factor 2A

Also known as: C10orf141, FAM196A, INSYN2

NCBI Gene: 642938 ENSG00000188916 UniProt: Q6ZSG2 OMIM: 617129

The protein functions as a scaffold component at inhibitory synapses, which dampen neuronal activity through postsynaptic hyperpolarization and are essential for precise neural signaling in the central nervous system. Mutations in this gene cause neurodevelopmental disorders with epilepsy, and inheritance follows an autosomal dominant pattern. This gene is highly constrained against loss-of-function variants, indicating that such mutations are likely to cause significant clinical effects.

Interpreting a novel variant

This gene is strongly intolerant of loss-of-function variation in the population, so LoF variants warrant close attention. No curated mechanism annotation is available — see the mechanism card for the computational prediction and its caveats.Based on population constraint only.
