A de novo splice donor mutation in the thrombopoietin gene causes hereditary thrombocythemia in a Polish family.

Identification of a Novel Splice Site Mutation in RUNX2 Gene in a Family with Rare Autosomal Dominant Cleidocranial Dysplasia

Introduction: Pathogenic variants of RUNX2, a gene that encodes an osteoblast-specific transcription factor, have been shown as the cause of CCD, which is a rare hereditary skeletal and dental disorder with dominant mode of inheritance and a broad range of clinical variability. Due to the relative lack of clinical complications resulting in CCD, the medical diagnosis of this disorder is challen...

The Difference in Initial Leukocyte Count, Bone Marrow Blast Cell Count and CD 34 Expression in Patients with Acute Myeloid Leukemia with and without NPM1 gene Mutation

Background: Mutation in NPM1 gene has been reported to be the most common genetic mutation in de novo acute myeloid leukemia (AML). AML with NPM1 gene mutation usually presents with higher initial leukocyte and blast cell counts and negative CD34 expression. We aimed to investigate the difference of initial leukocyte counts, bone marrow blast cell counts and expression of CD34 among patients wi...

A Novel Splice Site Mutation in HPS1 Gene is Associated with Hermansky-Pudlak Syndrome-1 (HPS1) in an Iranian Family

A Novel Splicesite Mutation in the EDAR Gene Causes Severe Autosomal Recessive Hypohydrotic (Anhidrotic) Ectodermal Dysplasia in an Iranian Family

Hypohidrotic ectodermal dysplasia (HED) is a rare congenital disorder arising from deficient development of ectoderm-derived structures including skin, nails, glands and teeth. The phenotype of HED is associated with mutation in EDA, EDAR, EDARADD and NEMO genes, all of them disruptingNF-κB signaling cascade necessary for initiation, formation and differentiation in the embryo and adult. ...

Evidence for a founder effect of the MPL-S505N mutation in eight Italian pedigrees with hereditary thrombocythemia.

BACKGROUND Hereditary thrombocythemia is a rare disease characterized by increased megakaryopoiesis and overproduction of platelets. Germ line mutations have been identified in the genes for thrombopoietin (THPO) and its receptor, MPL. A clustering of familial cases with the MPL-G1073A mutation that results in a serine to asparagine substitution (S505N) has been recently reported in Italy. Here...
