Potassium inwardly-rectifying channel, subfamily J, member 10

Th KCNJ10 gene encodes a member of the inward rectifier-type potassium channel family. Its presence in the kidney and in the central nervous system accounts for the comples symptoms of the EAST syndrome, an autosomal recessive disease caused by mutations of that gene.
