Presentation
The present study has pointed out a significant difference between the two syndromes. [ncbi.nlm.nih.gov]
Epistaxis was the most common presenting symptom. The youngest patients in the group presented with subdural hematomas before the age of 2. [bloodjournal.org]
Individuals with ADP deficient storage pool disease present a prolonged bleeding time due to impaired aggregation response to fibrillar collagen. [en.wikipedia.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]

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]
People with storage pool deficiencies may experience: Easy bruising Nose bleeds Bleeding from gums Heavy or prolonged menstrual bleeding (menorrhagia) or bleeding after childbirth Abnormal bleeding after surgery, circumcision, or dental work Diagnosis [wfh.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]

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]

Nystagmus

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]
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]
Therefore the following examples include: Platelet alpha-granules Gray platelet syndrome Quebec platelet disorder Dense granules δ-Storage pool deficiency Hermansky–Pudlak syndrome Chédiak–Higashi syndrome Platelet storage pool deficiency has no treatment [en.wikipedia.org]
Patients with platelet storage pool deficiencies may need to have treatment during dental or surgical procedures or after injuries or accidents. Platelets and other agents may be incorporated into treatment. [rarebleedingdisorders.com]
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]
While we describe a significant relationship with POTS and δ-SPD, this finding does not constitute an etiology for POTS. [forums.phoenixrising.me]
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]
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]
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]
