Blueprint Genetics Bone Marrow Failure Syndrome Panel
Bone Marrow Failure Syndrome Panel Test code: HE0801 Is a 135 gene panel that includes assessment of non-coding variants. Is ideal for patients with a clinical suspicion of inherited bone marrow failure syndromes. The genes on this panel are included in the Comprehensive Hematology Panel. About Bone Marrow Failure Syndrome Inherited bone marrow failure syndromes (IBMFS) are a diverse set of genetic disorders characterized by the inability of the bone marrow to produce sufficient circulating blood cells. Bone marrow failure can affect all blood cell lineages causing clinical symptoms similar to aplastic anemia, or be restricted to one or two blood cell lineages. The clinical presentation may include thrombocytopenia or neutropenia. Hematological manifestations may be accompanied by physical features such as short stature and abnormal skin pigmentation in Fanconi anemia and dystrophic nails, lacy reticular pigmentation and oral leukoplakia in dyskeratosis congenita. Patients with IBMFS have an increased risk of developing cancer—either hematological or solid tumors. Early and correct disease recognition is important for management and surveillance of the diseases. Currently, accurate genetic diagnosis is essential to confirm the clinical diagnosis. The most common phenotypes that are covered by the panel are Fanconi anemia, Diamond-Blackfan anemia, dyskeratosis congenita, Shwachman-Diamond syndrome and WAS-related disorders.

Cardiomyopathy in a Male Patient with Neutropenia and Growth Delay
Folsi et al. Italian Journal of Pediatrics 2014, 40:45 http://www.ijponline.net/content/40/1/45 ITALIAN JOURNAL OF PEDIATRICS CASE REPORT Open Access Cardiomyopathy in a male patient with neutropenia and growth delay Veronica Folsi1, Nunzia Miglietti1, Annamaria Lombardi1, Sara Boccacci1, Tatiana Utyatnikova1, Chiara Donati1, Livia Squassabia1, Laura Gazzola1, Ilaria Bosio1, Adele Borghi2, Veronica Grassi3, Lucia D Notarangelo3 and Alessandro Plebani1,4* Abstract Neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, ranging from severe (<500 neutrophils/mm3) to mild (500–1500 neutrophils/mm3), 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 to the circulating neutrophil counts. When neutropenia is detected, an attempt should be made to establish the etiology, and to distinguish acquired forms (the most frequent, including post viral neutropenia and autoimmune neutropenia) and congenital forms (rare disorders) that may be either isolated or part of a complex rare genetic disease. We report on a male patient initially diagnosed with isolated neutropenia who later turned out to be affected with Barth syndrome, a rare complex inherited disorder.

Abstract In this case report we describe a patient with cohen syndrome and severe neutropenia. The patient was found to have a mutation of previously undetermined significance in the ELANE gene and compound heterozygous mutations in the COH1 gene causing Cohen syndrome. While the mutation in ELANE may not have led to clinically significant neutropenia independently, the presence of this mutation in conjunction with mutations in COH1 led to neutropenia that was more severe than what is typically seen in Cohen syndrome. -

[email protected] Abstract Keywords Disease name and synonyms Definition Diagnostic criteria Differential diagnosis Etiology and pathogenesis Clinical manifestations Prevalence Course Treatment and therapeutic perspectives Preventive measures References Abstract In 1973, Cohen et al. described a new syndrome whose main features were obesity, hypotonia, mental retardation, characteristic craniofacial dysmorphism and abnormalities of the hands and feet. This syndrome is hereditary and transmitted as an autosomal recessive trait, with considerable variability of expression. The wide variety of manifestations observed, raises the possibility that not all of cases of Cohen syndrome correspond to the same process. It has been suggested that there are 2 types of Cohen syndrome, one with neutropenia and the other without neutropenia. Until now, nearly 100 cases have been reported. Orthodontic and orthopedic management as well as psychopedagogic measures and possible growth hormone therapy are necessary. Obesity progresses over time, along with the orthopedic alterations and oral problems, though the patient life expectancy is not altered in any significant way. Recently, characterization of a novel gene, COH1 (locus 8q22-q23) that is mutated in patients with Cohen syndrome has been reported. COH1 encodes a putative transmembrane protein which may be is involved in vesicle-mediated sorting and transport of proteins within the cell.
