ID, EPSRelevance to Autism
Rare mutations in the KCNJ10 gene have been identified with autism (Sicca et al., 2011). In particular, that study found two non-synonymous SNPs (P18Q and V84M) in unrelated individuals with a seizure disorder who also have ASD and ID. Both of these mutations were shown to be functional in heterologous systems. In addition, genetic association has been found between KCNJ10 and seizure susceptibility in patients with epilepsy (Buono et al., 2004).
Molecular Function
This gene encodes a member of the inward rectifier-type potassium channel family, characterized by having a greater tendency to allow potassium to flow into, rather than out of, a cell. The encoded protein may form a heterodimer with another potassium channel protein and may be responsible for the potassium buffering action of glial cells in the brain. Mutations in this gene have been associated with seizure susceptibility of common idiopathic generalized epilepsy syndromes.
