T. Usman, Yu, Y., Zhai, L., Liu, C., Wang, X., Wang, Y., Usman, T., Yu, Y., Zhai, L., Liu, C., Wang, X., and Wang, Y., Association of CD4 SNPs with fat percentage of Holstein cattle, vol. 15, p. -, 2016.

Cluster of differentiation 4 gene (CD4) is well known for its role in immunity, but its effects on production traits remain to be elucidated. The present study was designed to explore single nucleotide polymorphisms (SNPs) in the exons, flanking introns, and promoter of CD4, as well as to analyze their effects on milk production traits (percentage of protein, fat, and lactose; mastitis indicator traits somatic cell count; and somatic cell score).

Quantitative candidate gene association studies of metabolic traits in Han Chinese type 2 diabetes patients

F. J. Wei, Cai, C. Y., Yu, P., Lv, J., Ling, C., Shi, W. T., Jiao, H. X., Chang, B. C., Yang, F. H., Tian, Y., Li, M. S., Wang, Y. H., Zou, L., Shi, J. M., Chen, L. M., and Li, W. D., Quantitative candidate gene association studies of metabolic traits in Han Chinese type 2 diabetes patients, vol. 14, pp. 15471-15481, 2015.

Recent genome-wide association studies have identified many loci associated with type 2 diabetes mellitus (T2DM), hyperuricemia, and obesity in various ethnic populations. However, quantitative traits have been less well investigated in Han Chinese T2DM populations. We investigated the association between candidate gene single nucleotide polymorphisms (SNPs) and metabolic syndrome-related quantitative traits in Han Chinese T2DM subjects. Unrelated Han Chinese T2DM patients (1975) were recruited.

Association between RAGE gene polymorphisms and ulcerative colitis susceptibility: a case-control study in a Chinese Han population

Z. T. Wang, Wang, L. Y., Wang, L., Cheng, S., Fan, R., Zhou, J., and Zhong, J., Association between RAGE gene polymorphisms and ulcerative colitis susceptibility: a case-control study in a Chinese Han population, vol. 14, pp. 19242-19248, 2015.

Ulcerative colitis (UC) is an immune-related disease with genetic predisposition. The aim of this study was to investigate the association of three polymorphisms in the receptor for advanced glycation end-products (RAGE) gene with UC risk in a Chinese population. This case-control study involved 72 UC patients and 479 age- and gender-matched healthy controls. Genotyping was performed using the polymerase chain reaction-ligase detection reaction method. Data were analyzed using the Haplo.stats program.

Association of the VRK2 gene rs3732136 polymorphism with schizophrenia in a Northwest Chinese Han population

B. Zhang, Gao, C. Y., Zhang, H. B., Yang, B., Yin, J. F., Wei, S. G., Zhu, Y. S., Jia, X. N., and Li, S. B., Association of the VRK2 gene rs3732136 polymorphism with schizophrenia in a Northwest Chinese Han population, vol. 14, pp. 9404-9411, 2015.

Previous studies have found that the vaccinia related kinase 2 gene (VRK2) polymorphism was associated with schizophrenia (SCZ) in the worldwide population. This association was further supported by VRK2 mRNA expression patterns and brain structure variations. Here, we analyzed four single nucleotide polymorphisms (SNPs) of the VRK2 gene in a total population of 893 samples, consisting of 360 patients with SCZ and 533 healthy controls of Han Chinese descent using the SNPscan method. Single SNP, haplotype, and gender-specific association analyses were performed.
