Background: The variable numbers of tandem-repeat (VNTR) alleles at the phenylalanine hydroxylase (PAH) gene have been used in carrier detection and prenatal diagnosis in phenylketonuria families. This study was carried out to analyze VNTR alleles at the PAH gene in Iranian Azeri Turkish population. Methods: In this study, 200 alleles from general population were studied by PCR. Results: The fr...

BACKGROUND Susceptibility to beryllium (Be)-hypersensitivity (BH) has been associated with HLA-DP alleles carrying a glutamate at position 69 of the HLA-DP beta-chain (HLA-DPGlu69) and with several HLA-DP, -DQ and -DR alleles and polymorphisms. However, no genetic associations have been found between BH affected subjects not carrying the HLA-DPGlu69 susceptibility marker. METHODS In this repo...

common variable immunodeficiency (cvid) is an antibody deficiency syndrome that often co-occurs in families with selective iga deficiency (igad). this study was designed to investigate the frequency of dr and dq loci of hla class ii region in common variable immunodeficiency (cvid) patients. fifteen iranian patients with cvid or igad (mean age 14.6±5.4, range 4-25 years; 9 male and 6 female) an...

background: cytochrome p450 2c19 (cyp2c19) is a polymorphically expressed enzyme that shows marked interindividual and interethnic variation. cyp2c19*2 and cyp2c19*3 are the most frequently identified defective alleles in orientals and caucasian poor metabolizers (pm). the aim of this study was to investigate the frequencies of cyp2c19*1, cyp2c19*2 and cyp2c19*3 alleles and cyp2c19 genotypes in...
