'Teleostei Immunoglobulin Light IGL1 and IGL2 V, J and C Genes', the 12th report of the 'IMGT Locus in Focus' section, comprises 8 tables: (1) 'Teleostei IGL1V genes'; (2) 'Teleostei germline IGL1J genes'; (3) 'Teleostei IGL1C genes and alleles'; (4) 'Teleostei IGL2V genes'; (5) 'Teleostei germline IGL2J genes'; (6) 'Teleostei IGL2C genes and alleles'; (7) 'FR-IMGT and CDR-IMGT length of the Te...

Functional A and B alleles are distinguished at two critical sites in exon 7 of the human ABO blood group gene. The most frequent nonfunctional O alleles have one-base deletion in exon 6 producing a frameshift, and it has the A type signature in two critical sites in exon 7. Previous studies indicated that B and O alleles were derived from A allele in human lineage. In this study, we conducted ...

Variant D occurs frequently in Africans. However, considerably less RHD alleles have been described in this population compared with Europeans. We characterized 5 new RHD alleles, dubbed DAU-0 to DAU-4, that shared a T379M substitution and occurred in a cDe haplotype. DAU-1 to DAU-4 were detected in Africans with partial D phenotypes. They harbored one and 2 additional missense mutations, respe...

Several previous studies found an association of clinically diagnosed attention deficit hyperactivity disorder with long alleles of a variation in the DRD4 dopamine receptor gene exon III coding sequence. We evaluated the DRD4 polymorphism in a non-clinically selected sample of children for whom maternal reports of attention problems were available at 4 and 7 years of age. There was a significa...

This cross-sectional study enrolled 180 patients at a private family practice in Virginia. Total serum vitamin D concentrations were obtained weekly from January 30, 2013, through March 30, 2013, in consecutive patients regularly scheduled for laboratory work at the practice. Patients were categorized into 2 groups and analyzed for variant alleles in vitamin D receptor ( VDR; rs2228570), cytoch...

To increase the existent genetic variability in cysteine proteases, a polymorphism study was performed in Haemonchus contortus by comparing 2 different strains of the parasite: North American (NA) and Spanish (SP) strains. For this purpose, the polymorphism of 5 previously reported genes (AC-1, AC-3, AC-4, AC-5 and GCP-7) were analysed by PCR-SSCP and sequencing procedures. Based on the SSCP re...

Abstract Lipoxygenase (LOX) activity is closely related to wheat processing and storage quality. In the present research, ten cultivars were used compare effects of genotype, location, year, their interactions on LOX activity. Furthermore, 123 evaluated for with 192 simple sequence repeat (SSR) markers identify elite alleles The results indicated that was highly affected by genotype (variety) t...

CONTEXT Although tuberculosis (TB) is the leading worldwide cause of death due to an infectious disease, the extent to which progressive clinical disease is associated with genetic host factors remains undefined. OBJECTIVE To determine the distribution of HLA antigens and the frequency of 2 alleles of the tumor necrosis factor alpha (TNF-alpha) gene in unrelated individuals with clinical TB (...

Human leukocyte antigen (HLA) genes have been associated with susceptibility and protection against a number of cancers. Here we used an immunogenetic epidemiological approach to evaluate the overall influence 127 HLA Class I II alleles on 30 types cancer. We found preponderance protective (negatively correlated cancer prevalences), especially for I. Of cancers investigated, 13 were mostly effe...
