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....

PURPOSE The gene coding cytochrome P4501B1 (CYP1B1) has been shown to be a major cause of primary congenital glaucoma in the Iranian population. More recently it was shown to also be important in juvenile-onset open angle glaucoma (JOAG). We aimed to further investigate the role of CYP1B1 in a larger cohort of primary open angle glaucoma (POAG) patients which included late-onset patients. We al...

abstract   objective: in this study, we evaluated pten mutations in cowden disease and juvenile polyposis syndrome. pten mutations were detected, cancer and other phenotypes associated with each of these mutations were characterized and loss of wild type pten allele in the associated tumors was demonstrated. methods: out of 9 patients included in this study, 8 had juvenile polyposis and 1 had c...

background: heterogeneous mutations in the human coagulation factor ix gene lead to an x-linked recessive bleeding disorder known as hemophilia b. the disease is distributed worldwide with no ethnic or geographical priority. materials and methods: the aim of this study was to characterize the factor ix gene mutations in 28 unrelated iranian hemophilia b patients. polymerase chain reaction (pcr)...

Primary microcephaly (MCPH) is a genetic disorder in which affected individuals present with a head circumference 3 standard deviations (SDs) below the age- and sex-related mean and is accompanied by mental retardation without further associated malformations. Here we report a patient with sporadic MCPH from Northwest of Iran who was investigated for MCPH1 locus. Clinical examination and karyot...

OBJECTIVE Methylmalonic acidura (MMA) is a rare autosomal recessive inborn error of metabolism. In this study we present a novel nucleotide change in the mutase (MUT) gene of two unrelated Iranian pedigrees and introduce the methods used for its functional analysis. MATERIALS AND METHODS Two probands with definite diagnosis of MMA and a common novel variant in the MUT were included in a descr...

At physical examination, the patient had a weight of 4,750g, a body length of 52cm, and his blood pressure was 80/60mmHg. Laboratory data showed blood urea nitrogen (BUN) of 7mg/dL, creatinine (Cr) of 0.39mg/dL, total protein of 5g/dL, and albumin of 2.36g/dL. Other laboratory tests revealed the following values: cholesterol: 152mg/dL, triglyceridemia: 111 mg/dL, calcium: 7.5mg/dL, P: 5.6mg/dL,...
