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.

Journal:

 

The Gray Platelet Syndrome (GPS) is a rare inherited bleeding disorder characterized by deficiency of platelet α-granules, macrothrombocytopenia and marrow fibrosis. The autosomal recessive form of GPS is linked to loss of function mutations in NBEAL2, which is predicted to regulate ...

Journal:

 

During the analysis of a whole genome ENU mutagenesis screen for thrombosis modifiers, a spontaneous 8 base pair (bp) deletion causing a frameshift in exon 27 of the Nbeal2 gene was identified. Though initially considered as a plausible thrombosis modifier, this Nbeal2 mutation failed ...

Should any genetic defect affecting α-granules in platelets be classified as gray platelet syndrome?
 

Author(s): Alan T Nurden, Paquita Nurden

Journal: Am. J. Hematol.. 2016 Jul;91(7):714-8.

 

There is much current interest in the role of the platelet storage pool of α-granule proteins both in hemostasis and non-hemostatic events. As well as in the arrest of bleeding, the secreted proteins participate in wound healing, inflammation, and innate immunity while in pathology ...
