Hermansky-Pudlak syndrome

Common Name(s)

Hermansky-Pudlak syndrome

Hermansky-Pudlak syndrome is a multisystem, genetic condition characterized blood platelet dysfunction with prolonged bleeding, visual impairment, and abnormally light coloring of the skin, hair, and eyes (oculocutaneous albinism). Long-term sun exposure greatly increases the risk of skin damage and skin cancers. Some individuals have colitis, kidney failure, and pulmonary fibrosis. Symptoms of pulmonary fibrosis usually appear during the early thirties and rapidly worsen. This condition is inherited in an autosomal recessive fashion.

There are eight different types of Hermansky-Pudlak syndrome, which can be distinguished by their signs and symptoms and underlying genetic cause. Types 1 and 4 are the most severe forms. Types 1, 2, and 4 are the only types associated with pulmonary fibrosis. Individuals with type 3, 5, or 6 have the mildest symptoms of all the types. Little is known about the signs, symptoms, and severity of types 7 and 8.
