Gray Platelet Syndrome

Common Name(s)

Gray Platelet Syndrome

Gray platelet syndrome (GPS) is a rare inherited bleeding disorder characterized by platelets that have a gray appearance, severe thrombocytopenia, myelofibrosis, and splenomegaly. About 60 cases from various populations around the world have been described in the literature to date. GPS results from the absence or reduction of alpha-granules in platelets, which store proteins that promote platelet adhesiveness and wound healing when secreted during an injury. GPS is caused by mutations in the NBEAL2 gene and inherited in an autosomal recessive manner.

The gray platelet syndrome is a hereditary, usually autosomal recessive bleeding disorder caused by a deficiency of alpha granules in platelets. We detected a nonsense mutation in the gene encoding the transcription factor GFI1B (growth factor independent 1B) that causes autosomal ...
