OMIM : ⁵⁸ Prolidase deficiency is a rare autosomal recessive multisystem disorder associated with massive imidodipeptiduria and lack of or reduced prolidase activity in erythrocytes, leukocytes, or cultured fibroblasts. The disorder is clinically heterogeneous and severity varies widely. Features include chronic, slowly healing ulcerations, mainly on the legs and feet. The ulcers are often preceded by other dermatologic manifestations that may occur anywhere and include erythematous papular eruptions, telangiectases with pruritus and photosensitivity, impetigo-like eruptions, pruritic eczematous lesions, and necrotic papules. Mild to severe mental retardation is often a feature, and recurrent respiratory tract infections, sometimes fatal, are common. Facial dysmorphism may include low hairline and hirsutism, saddle nose, ocular hypertelorism, micrognathia, a high-arched palate, mandibular protrusion, and exophthalmos. Clinical manifestations are usually detectable after birth or in early childhood, but late-onset cases have been reported (summary by Lupi et al., 2008). (170100)

MalaCards based summary : Prolidase Deficiency, also known as hyperimidodipeptiduria, is related to parkinson disease, late-onset and glaucoma-related pigment dispersion syndrome, and has symptoms including petechiae of skin An important gene associated with Prolidase Deficiency is PEPD (Peptidase D). Affiliated tissues include skin, liver and spleen, and related phenotypes are hearing impairment and recurrent respiratory infections

Genetics Home Reference : ²⁶ Prolidase deficiency is a disorder that causes a wide variety of symptoms. The disorder typically becomes apparent during infancy. Affected individuals may have enlargement of the spleen (splenomegaly); in some cases, both the spleen and liver are enlarged (hepatosplenomegaly). Diarrhea, vomiting, and dehydration may also occur. People with prolidase deficiency are susceptible to severe infections of the skin or ears, or potentially life-threatening respiratory tract infections. Some individuals with prolidase deficiency have chronic lung disease.

NIH Rare Diseases : ⁵⁴ 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.

UniProtKB/Swiss-Prot : ⁷⁶ Prolidase deficiency: A multisystem disorder associated with massive iminodipeptiduria and lack of or reduced prolidase activity in erythrocytes, leukocytes, or cultured fibroblasts. Clinical features include skin ulcers, developmental delay, recurrent infections, and a characteristic facies.
