BACKGROUND A previous genome-wide linkage study of alcohol dependence in multiplex families found a suggestive linkage result for a region on Chromosome 1 near microsatellite markers D1S196 and D1S2878. The KIAA0040 gene has been mapped to this region (1q24 - q25). A recent genome-wide association study using SAGE (the Study of Addiction: Genetics and Environment) and COGA (Collaborative Study ...
T helper (h) lymphocytes in pathogenic immune response at mucosal effector site play a key role in IgA nephropathy (IgAN). We evaluated the impact of some Th1/Th2/Th3/T(R)-type, and of monocyte/macrophage cytokines on IgAN susceptibility with a family-based association study including 53 patients, 45 complete trios, 4 incomplete trios and 36 discordant siblings. Cytokine gene polymorphisms with...
In recent years, a myriad of new statistical methods have been proposed for detecting associations of rare single-nucleotide variants (SNVs) with common diseases. These methods can be generally classified as 'collapsing' or 'haplotyping' based. The former is the predominant class, composed of most of the rare variant association methods proposed to date. However, recent works have suggested tha...
Suicidal behavior (SB) has a complex etiology involving genes and environment. One of the genetic components in SB could be copy number variations (CNVs), as CNVs are implicated in neurodevelopmental disorders. However, a recently published genome-wide and case-control study did not observe any significant role of CNVs in SB. Here we complemented these initial observations by instead using a fa...
RATIONALE It has been shown that country living protects against asthma, which may be explained by microbial exposures. OBJECTIVES To study whether single nucleotide polymorphisms (SNPs) in CD14 and Toll-like receptor (TLR) 2, TLR4 and TLR9 genes are associated with asthma in adults, and whether these SNPs modify associations between country living and asthma. METHODS Twenty-five SNPs in CD...
Non-syndromic intellectual disability (NSID) is mental retardation in persons of normal physical appearance who have no recognisable features apart from obvious deficits in intellectual functioning and adaptive ability; however, its genetic etiology of most patients has remained unknown. The main purpose of this study was to fine map and identify specific causal gene(s) by genotyping a NSID fam...
BACKGROUND Autism is a neurodevelopmental disorder with a high estimated heritability. ATP2B2, located on human chromosome 3p25.3, encodes the plasma membrane calcium-transporting ATPase 2 which extrudes Ca(2+) from cytosol into extracellular space. Recent studies reported association between ATP2B2 and autism in samples from Autism Genetic Resource Exchange (AGRE) and Italy. In this study, we ...
For the sour water strippers in petroleum refinery plants, three prediction models were developed first, including estimators of feed concentrations using convenient online measurements, minimum reboiler duty and corresponding internal temperature at a specific location (Tstage,29). Feedforward control schemes based on these models. Four categories schemes, feedforward, feedback, feedback with ...
For genome-wide association studies in family-based designs, we propose a powerful two-stage testing strategy that can be applied in situations in which parent-offspring trio data are available and all offspring are affected with the trait or disease under study. In the first step of the testing strategy, we construct estimators of genetic effect size in the completely ascertained sample of aff...
PURPOSE Recent work has suggested that insulin-like growth factor 1 (IGF-1) gene polymorphisms are genetically linked with high-grade myopia (HM), which is a complex-trait eye disorder in which numerous candidate loci and genes are thought to play a role. We investigated whether the IGF-1 single nucleotide polymorphisms (SNPs) rs6214, rs10860860, and rs2946834 are associated with HM (≤-6.0 diop...
