Introduction: The Thiamine Transporter gene SLC19A2 is the only gene known to be associated with TRMA.  This syndrome is a trial clinical characterized by megaloblastic anemia, nonautoimmune diabetes mellitus and sensory-neural hearing loss. Methods: Described here are three children from consanguineous Iranian families with thiamine – responsive megaloblastic anemia (TRMA) or Rogers' syndrome....

Backgrounds: Hypohidrotic ectodermal dysplasia (HED) is a rare genetic disorder, distinguished by hypotrichosis, hypohidrosis, and hypodontia. HDE can be inherited in X-linked recessive manner as a result of mutations in the ectodysplasin A (EDA) gene as well as autosomal dominant and autosomal recessive manners both of them caused by mutations in EDA receptor (EDAR) and EDAR-associated death d...

congenital recessive myotonia is a rare genetic disorder caused by mutations in clcn1, which codes for the main skeletal muscle chloride channel clc-1. more than 120 mutations have been found in this gene. the main feature of this disorder is muscle membrane hyperexcitability. here, we report a 59-year male patient suffering from congenital myotonia. he had transient generalized myotonia, which...

severe congenital neutropenia (scn) is a rare primary immunodeficiency. different genes are found to be associated with scn, including ela2, hax1, was, gfi1, g-csfr. also, recently g6pc3 as a rare gene in scn has been reported. patients with g6pc3 often have cardiac and/or urogenital malformations. two patients with   persistent   severe   neutropenia,   recurrent   infections   and   maturatio...

Sotos syndrome is an autosomal dominant genetic disorder caused by mutations in the NSD1 gene. In this study, we report a case of preterm infant. The main clinical manifestations were severe bronchopulmonary dysplasia, congenital heart disease, difficulty feeding, and characteristic facial appearance. gene mutation was located at 177251854 on chromosome 5, identified as shear mutation, c.4765+1...
