Prolidase deficiency is a rare metabolic condition characterized by skin lesions, recurrent infections, unusual facial features, variable intellectual disability, enlargement of the liver (hepatomegaly) with elevated liver enzymes, and enlargement of the spleen (splenomegaly). Symptoms typically present during infancy and vary greatly among affected individuals. The condition is caused by mutations in the PEPD gene. It is inherited in an autosomal recessive pattern. Treatment for prolidase deficiency is symptomatic and supportive and often requires the expertise of a multidisciplinary team.
