where J and N are positive integers, and the X's are real or complex constants. It is assumed that we do not have XON = XiN = .. = XJN, and that we do not have XOn = Xln = . . . = )kXj * Ofor any n < N. It is also assumed that no two terms in the right-hand member of (1) are identical or differ only by a constant factor. The work reported here is essentially a generalization, in one direction, ...

Glucose-6-phosphatase-β (G6Pase-β or G6PC3) deficiency, also known as severe congenital neutropenia syndrome 4, is characterized not only by neutropenia but also by impaired neutrophil energy homeostasis and functionality. We now show the syndrome is also associated with macrophage dysfunction, with murine G6pc3(-/-) macrophages having impairments in their respiratory burst, chemotaxis, calcium...

Severe congenital neutropenia (SCN) is a rare primary immunodeficiency disease. Different genes are found to be associated with SCN, including ELA2, HAX1, WAS, GFI1, G-CSFR and G6PC3. The aim of this study was to find different gene mutations responsible for SCN in Iranian patients. Twenty-seven patients with SCN referred to Immunology, Asthma and Allergy Research Institute during a five year p...

Neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, ranging from severe (<500 neutrophils/mm(3)) to mild (500-1500 neutrophils/mm(3)), which may also affect other organ systems such as the pancreas, central nervous system, heart, muscle and skin. Neutropenia can lead to life-threatening pyogenic infections whose severity is roughly inversely proportional ...

The underlying cause of neutropenia may be difficult to determine due to similar clinical presentation in many neutropenic conditions. The neutrophil protein hCAP-18 (pro-LL-37) is a major component of neutrophil secondary granules and in this prospective study we assessed the use of hCAP-18 levels in blood plasma for differential diagnosis of neutropenic patients (n = 133) of various aetiologi...

BACKGROUND The purpose of this study was to describe the natural history of severe congenital neutropenia (SCN) in 14 patients with G6PC3 mutations and enrolled in the French SCN registry. METHODS Among 605 patients included in the French SCN registry, we identified 8 pedigrees that included 14 patients with autosomal recessive G6PC3 mutations. RESULTS Median age at the last visit was 22.4 ...
