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)
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)
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)
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)
The human thyroxine-binding prealbumin (TBPA) gene was examined for restriction fragment length polymorphism (RFLP) in normal subjects and a subject with euthyroid hyperthyroxinaemia, due to increased thyroxine binding by TBPA, using 16 restriction enzymes. Only Taq I and Msp I were shown to detect RFLPs. In a male of the normal population and one of his(More)
The nucleotide (nt) variations in the promoter region of the gamma-globin genes, HS-111 and 3'HS1 regions, were studied in Iranian patients with beta-thalassemia intermedia (beta-TI), beta-thalassemia major (beta-TM) and healthy individuals. Of the five nt variations at the 5' end of the (A)gamma-globin gene, -369 (C>G), -611 (-T) and -603/604 (GA>AG) were(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)

We studied 325 thalassemia intermedia patients from Iran, India, Pakistan, Thailand, Mauritius and Cyprus to examine factors which influence the phenotype. The beta-thalassemia (thal) mutations were determined for 219 beta-thal/beta-thal and 106 beta-thal/Hb E [beta26(B8)Glu-->Lys, GAG-->AAG] thalassemia intermedia patients. Thirty-one different mutations(More)
