MedlinePlus Genetics: 42 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.Characteristic facial features in people with prolidase deficiency include prominent eyes that are widely spaced (hypertelorism), a high forehead, a flat bridge of the nose, and a very small lower jaw and chin (micrognathia). Affected children may experience delayed development, and about 75 percent of people with prolidase deficiency have intellectual disability that may range from mild to severe.People with prolidase deficiency often develop skin lesions, especially on their hands, feet, lower legs, and face. The severity of the skin involvement, which usually begins during childhood, may range from a mild rash to severe skin ulcers. Skin ulcers, especially on the legs, may not heal completely, resulting in complications including infection and amputation.The severity of symptoms in prolidase deficiency varies greatly among affected individuals. Some people with this disorder do not have any symptoms. In these individuals the condition can be detected by laboratory tests such as newborn screening tests or tests offered to relatives of affected individuals. MalaCards based summary: Prolidase Deficiency, also known as hyperimidodipeptiduria, is related to paroxysmal extreme pain disorder and splenomegaly, and has symptoms including petechiae of skin An important gene associated with Prolidase Deficiency is PEPD (Peptidase D). Affiliated tissues include skin, spleen and liver, and related phenotypes are hearing impairment and depressed nasal bridge OMIM®: 57 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) (Updated 08-Dec-2022) GARD: 19 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 genetic changes in the PEPD gene. It is inherited in an autosomal recessive pattern. Disease Ontology: 11 An amino acid metabolic disorder characterized by massive imidodipeptiduria, chronic and slowly healing ulcerations, recurrent infections, dysmorphic facial features, variable cognitive impairment, splenomegaly, and lack of or reduced prolidase activity that has material basis in homozygous or compound heterozygous mutation in PEPD on chromosome 19q13.11. UniProtKB/Swiss-Prot: 73 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. Orphanet: 58 Prolidase deficiency is an inherited disorder of peptide metabolism characterized by severe skin lesions, recurrent infections (involving mainly the skin and respiratory system), dysmorphic facial features, variable cognitive impairment, and splenomegaly.
