Living with Prolidase deficiency
A rare genetic condition with a wide range of symptoms, including skin sores, infections, and an enlarged spleen.
Understanding Prolidase deficiency
People may have an enlarged spleen, sometimes with an enlarged liver. Diarrhea, vomiting, and dehydration can occur, along with skin or ear infections. Skin sores, especially on the hands, feet, lower legs, and face, can range from a mild rash to severe ulcers. Some people have delayed development or intellectual disability. Some people have no symptoms, and it is found by lab tests.
Signs & symptoms
Symptoms vary a lot from person to person. GARD lists these among the most common:
- Skin sores or crusting rash
- Enlarged spleen and sometimes liver
- Frequent infections of the skin or ears
- Widely spaced eyes and a flat nose bridge
- Delayed development or intellectual disability
- Hearing problems
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
