ADIPOQ, KCNJ11 and TCF7L2 polymorphisms in type 2 diabetes in Kyrgyz population: A case‐control study

The aim of this study was to ascertain the polymorphic markers profile of ADIPOQ,KCNJ11 and TCF7L2 genes in Kyrgyz population and to analyze the association of polymorphic markers and combinations of ADIPOQ gene's G276T locus, KCNJ11 gene's Glu23Lys locus and TCF7L2 gene's VS3C>T locus with type two diabetes (T2D) in Kyrgyz population. In this case‐control study, 114 T2D patients 109 non‐diabetic participants were genotyped using polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP). Two individual polymorphisms (ADIPOQ rs1501299, KCNJ11 rs5219) were found to be associated with T2D. We found two (Lys23Lys/CC and Glu23Lys/CT) of the overall nine combinations, which were more prevalent in T2D group compared to controls (χ2 = 4.21, P = 0.04). Lys23Lys/CC combination was associated with a 2.65‐fold increased likelihood of T2D (OR = 2.65, 95% CI 1.12‐6.28), whereas the Glu23Lys/CT combination also increased such likelihood (OR = 3.88, 95% CI 1.27‐11.91). This study demonstrated some association of 276T allele and ADIPOQ gene G276T heterozygous genotype as well as KCNJ11 gene 23Lys allele with T2D in ethnic Kyrgyz, but study results should be interpreted with caution because of the limited statistical power

Molecular characterization of a virulent strain of Newcastle disease virus isolated from a diseased chicken in Kyrgyzstan in 2016

Newcastle disease (ND) is a contagious viral disease affecting birds throughout the world and causing economic losses in the poultry industry. At present, little is known about the genetic causes of the ND outbreak that occurred in commercial poultry farms in Kyrgyzstan in 2016. In the current study, we isolated and confirmed a strain of ND virus (NDV) isolated from one out of two samples obtained from an unvaccinated flock. Based on phylogenetic analyses, this NDV strain was clustered in the class II subgenotype VIId and was closely related to the Chinese NDV isolate. Phylogenetic analyses also revealed that the isolated NDV strain has an origin different from the four NDV strains previously identified in Kyrgyzstan. According to a multibasic amino acid (aa) sequence at the F0 proteolytic cleavage site (112R-R-Q-K-R-F117), the NDV isolate was determined as a virulent strain. Several mutations in the neutralizing epitopes (notably, E347→K) and the global head were observed in the hemagglutininneuraminidase protein of the new isolate. The present study represents the first molecular characterization of the coding region of NDV genome obtained from Kyrgyzstan in 2016. This essential information may be useful for ND diagnostics and control
