Dense granules were normally present. Platelet aggregation with collagen was severely decreased, as was the response to convulxin (Cvx), a GPVI agonist. [ncbi.nlm.nih.gov]

You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]

From the clinical point of view, the bleeding tendency in this syndrome generally varies from mild to moderate, and no specific treatment is usually needed. [ncbi.nlm.nih.gov]

Treatment There is no curative treatment for gray platelet syndrome although it can be managed. Patients must avoid medications that impair functioning of platelets such as aspirin. [medigest.uk]

Newer therapies such as recombinant activated factor VIIa (rFVIIa) may have a role in some platelet disorders. [ 13 ] Prognosis [ 2 ] The overall prognosis is good. No fatal bleeds have been reported. [patient.info]

The prognosis is generally good The factors that create a very favorable outcome are when GPS is detected early and careful medical follow-up with appropriate and timely treatment is given If the platelet count is less than 30,000/microliter, then a severe [dovemed.com]

Plasma exchange therapy, introduced 30 years ago, has dramatically improved the prognosis for patients with TTP. [emedicine.medscape.com]

(Etiology) Anomalous genetic mutations in gene ‘NBEAL2’ is said to cause Grey Platelet Syndrome. [dovemed.com]

Although the experiment did not address the function of α-granules in thrombocytes, these results support the essential role of the Nbeal2 protein in thrombopoiesis and the etiology of GPS. [ncbi.nlm.nih.gov]

The etiology of the progressive nature of thrombocytopenia in GPS remains to be determined (worsening myelofibrosis and splenic enlargement with more platelet consumption). Our data show that myelofibrosis affects the majority (88%) of GPS patients. [bloodjournal.hematologylibrary.org]
