Inositol monophosphatase 3 also known as inositol monophosphatase domain-containing protein 1 (IMPAD1) is an enzyme that in humans is encoded by the IMPAD1 gene.^[5]

This gene encodes a member of the inositol monophosphatase family. The encoded protein is localized to the Golgi apparatus and catalyzes the hydrolysis of phosphoadenosine phosphate (PAP) to adenosine monophosphate (AMP).^[5]

Clinical significance

Mutations in this gene are a cause of GRAPP type chondrodysplasia with joint dislocations, and a pseudogene of this gene is located on the long arm of chromosome 1.^[5]
