Presentation
Epistaxis was the most common presenting symptom. The youngest patients in the group presented with subdural hematomas before the age of 2. [bloodjournal.org]
The present study is the first to document a severe decrease in both platelet α granules and dense bodies in four members in three generations of the same family. [iths.pure.elsevier.com]
The present study has pointed out a significant difference between the two syndromes. [ncbi.nlm.nih.gov]
Individuals with ADP deficient storage pool disease present a prolonged bleeding time due to impaired aggregation response to fibrillar collagen. [en.wikipedia.org]
Hematological
- Easy Bruising
An ELISA assay was used to determine serotonin (5HT) concentration in PLs and medical record review was employed to collect patients' clinical symptoms.The most common bleeding symptom was easy bruising (71%) but frequent nose bleeds, heavy menstrual [ncbi.nlm.nih.gov]
The most common bleeding symptom was easy bruising (71%) but frequent nose bleeds, heavy menstrual bleeding, and a family history of bleeding were also commonly reported. Definitely fits me. Interesting. [forums.phoenixrising.me]
Classically, the clinical features of storage pool disorders include nosebleeds (epistaxis), abnormally heavy or prolonged menstruation (menorrhagia), easy bruising, recurrent anemia, and obstetric or surgical bleeding. [diseaseinfosearch.org]
Patients having SPD often present with a history of easy bruising, frequent epistaxis, and prolonged bleeding times with or without abnormal aggregation tests. Both hereditary and acquired etiologies have been reported. [utoledo.edu]
Typically, easy bruising, petechiae, epistaxis, and mucocutaneous bleeding are observed in affected patients. The platelet defects are classified into disorders affecting either platelet surface receptors or intracellular organelles of platelets. [doi.org]
Psychiatrical
- Suggestibility
Seventeen patients (35%) had both decreased ATP release and decreased numbers of dense granules, suggesting the presence of a storage pool defect. [ncbi.nlm.nih.gov]
Efforts to differentiate this disorder from other hypogranular platelets syndromes in the present investigation suggested that the α granules and dense bodies become connected to channels of the open canalicular system (OCS) and lose their contents to [iths.pure.elsevier.com]
As a result we suggested that the Paris-Trousseau syndrome and the Jacobsen syndrome were probably identical disorders. [experts.umn.edu]
Neurologic
- Nystagmus
Hermansky Pudlak Syndrome Autosomal recessive Disorder Oculocutaneous albinism Neurologic Dysfunction Giant cytoplasmic leukocyte inclusions Severe immunodeficiency Autosomal recessive disorder Common in NW Puerto Rico Oculocutaneous albinism Rotary nystagmus [clinicaladvisor.com]
Reduced iris pigmentation may be associated with nystagmus, and visual acuity may be impaired. [orpha.net]
Patients have nystagmus and easy bruisability. Pulmonary fibrosis is a severe complication in many patients. Granulomatous colitis occurs in 10%-20% of patients. Eight different genes are known to cause HPS when mutated (HPS1 – HPS8). [genedx.com]

- Absent A-Waves
Adrenaline: Absent second wave aggregation [i.e. first wave only] with adrenaline. However this also occurs in 10-15% of healthy individuals. [practical-haemostasis.com]
Treatment
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]
Most people with storage pool deficiencies only need treatment during surgical procedures (including dental work) and after injury or trauma. [wfh.org]
Management and treatment There is no specific treatment but management involves anticipating and preventing risks of bleeding (e.g. possible platelet transfusions before surgery). Treatment may include administration of desmopressin. [orpha.net]
Treatments may be given by injection, nasal spray, or pills. The treatment for VWD depends on the type and severity of the bleeding disorder. For minor bleeds, treatment might not be needed. [glhf.org]
Prognosis
Prognosis Prognosis is generally good early in life when thrombocytopenia is mild. GPS patients with platelet counts less than 30,000/microliter are at risk for life-threatening bleeding. [orpha.net]
Prognosis The prognosis is very variable and will depend on the underlying condition. [patient.info]

Etiology
Abstract Mechanisms have been postulated to explain postural orthostatic tachycardia syndrome (POTS), however, the etiology of this often debilitating disorder remains unknown. [ncbi.nlm.nih.gov]
Both hereditary and acquired etiologies have been reported. Chédiak-Higashi, Grey Platelet, Hermansky-Pudlak, and Wiskott-Aldrich syndromes are examples of hereditary SPDs. [utoledo.edu]
While we describe a significant relationship with POTS and δ-SPD, this finding does not constitute an etiology for POTS. [forums.phoenixrising.me]
Etiology GPS is caused by mutations in the NBEAL2 gene. Absence or marked reduction of alpha-granules in platelets underlie the disorder. [orpha.net]
Epidemiology
Summary Epidemiology Exact prevalence of the disorder is not known. About 60 cases from various populations around the world have been described in the literature to date. It affects males and females equally. [orpha.net]

All of the patients were primarily managed by preventive measures and antifibrinolytic agents. Platelet transfusions have been reserved for life threatening bleeds or surgical procedures. [bloodjournal.org]
The scarring associated with myelofibrosis damages bone marrow, preventing it from making enough blood cells. [icdlist.com]
The goal of treatment is to prevent bleeds and the damage associated with bleeding. Quality medical care from health care providers with expertise in this bleeding disorder can help prevent many serious problems. [glhf.org]
