Prolidase deficiency (PD) is a severe autosomal recessive disorder due to the lack of prolidase (EC:3.4.13.9), a peptidase with a preference for Xaa-Pro dipeptide substrates that participates in collagen metabolism and in the terminal degradation of endogenous and dietary proteins. It typically begins in childhood and common symptoms include chronic intractable skin ulcerations and mental retardation. Mutations in prolidase gene causing the reduction or the loss of prolidase activity are responsible for PD.
