The base sequence of cDNA encoding the complete human liver cysteine dioxygenase type I (CDO-I; EC 1.13.11.20) message, and the derived amino-acid sequence are reported. CDO-I is encoded on a single mRNA species (approx. 1.5 kb). Human CDO-I clones were identified by screening a liver cDNA library, and inserts were isolated and sequenced. In addition, human(More)
PURPOSE To determine the prevalence and geographic distribution of thalassemia and to evaluate the success of the thalassemia prevention and treatment programs in Iran. METHODS Data were obtained from the National Thalassemia Registry of Iran, Iranian Blood Transfusion Organization, genetic laboratories involved in prenatal diagnosis, related(More)
Prometaphase and metaphase chromosome analyses performed on 70 consecutive men with primary infertility (for a period of at least 2 years) revealed 8 (11.42%) men with some kind of chromosomal abnormality. The highest frequency of abnormal karyotypes (10%) was found among patients with azoospermia and the most frequent anomaly was 47, XXY chromosomal(More)
Identification of molecular basis of phenylketonuria (PKU) in Iran has been accomplished through the analysis of 248 unrelated chromosomes from 124 Iranian classic PKU subjects. Phenylalanine hydroxylase (PAH) gene mutations were analyzed through a combined approach in which p.S67P, p.R252W, p.R261Q, p.R261X, p.L333F, IVS10-11G>A, IVS11+1G>C, p.L364del,(More)
Amplification and sequencing of the four transthyretin (TTR) exons of a subject with a variant TTR with four-fold increased affinity for thyroxine revealed a heterozygous G to A point mutation at base 7 of exon 2. This results in a serine for glycine change at residue 6 of the mature TTR monomer. No other mutations were found in any exon. Amplification and(More)

INTRODUCTION Studies have shown different types of RAS mutations in human bladder tumors with a wide range of mutation frequencies in different patient populations. This study aimed to assess the frequency of specific-point mutations in the RAS gene family of a group of Iranian patients with bladder cancer. MATERIALS AND METHODS We examined the tumor(More)
Mutations in the RB1 gene lead to retinoblastoma, which is the most common intraocular tumor in children under the age of 6. In the present survey, the mutations of 18 unrelated Iranian retinoblastoma patients were characterized. Mutation analysis of the RB1 gene was performed in patients by sequencing all coding regions and by multiplex ligation(More)
BACKGROUND Infertility affects approximately 10%-15% of couples in reproductive age. In half of the couples, causes are male-related, associated with impaired spermatogenesis. There is a complex correlation between genetics and infertility. Several factors affect on gametogenesis, from which factors that lead to chromosomal abnormalities are one of the best(More)
BACKGROUND Recurrent pregnancy loss (RPL) defined by two or more failed pregnancies before 20 weeks of gestation. Several factors play a role in RPL including thrombophilic conditions which can be influenced by gene polymorphisms. Plasminogen activator inhibitor-1 (PAI-1) and angiotensin converting enzyme (ACE) genes are closely related to fibrinolytic(More)
