Project description:To reveal the risk CNVs of SZ in Chinese population, we recrited and enrolled 100 Chinese family trios with a schizophrenia affected children and both of their father and mother. SZ was diagnosed according to DSM-IV criteria by two independent psychiatrists. There gDNA we screen the genome-wide CNV using Agilent SurePrint G3 Human CGH Microarray Kit (1x1M) and Agilent sex-matched human DNA was used as reference. The CNV were called by ADM-2 statistical algorithms with a threshold of 6.0. We compared the burden of large rare CNVs and found that SZ probands carried more duplications and less deletions. Furtherly, we performed familial inheritance analysis of transmission disequilibrium and de novo CNV detection, validated several associated CNV loci with SZ susceptibility and also identify eight novel loci conferring risk of SZ
Project description:Finding gene associations in rare diseases is frequently hampered by the reduced numbers of patients accessible. Conventional gene-based association tests rely on the availability of large cohorts, which constitutes a serious limitation for its application in this scenario. To overcome this problem we have used here a combined strategy in which a functional association study (pathway-based analysis) has been conducted to prioritize candidate genes in a Spanish cohort of 53 trios of short-segment Hirschsprung's disease that have been further validated in a larger population of 146 trios. The study revealed a strong association of 10 gene ontology (GO) modules related to signal transduction and its regulation, enteric nervous system (ENS) formation and other HSCR-related processes to the disease. A total of 10 new loci among the preselected candidates were found to be significantly associated to HSCR. This approach, based on the study of functionally-related gene sets, requires of lower sample sizes and opens new opportunities for the study of rare diseases.
Project description:Comparison of whole genome exome array CGH to a commercial SNP array for detection of de novo and homozygous copy number variants in 99 autism simplex trios. Will update once manuscript is prepared.
Project description:PKD2 Arg803* is the most common mutation in Taiwan ADPKD Cohort. Genotyping of 96 PKD2 Arg803* individuals was performed in Axiom Genome-Wide TWB 2.0 Array Plate to study the existence of founder mutation in Taiwan
Project description:Although smoking is the major risk factor for lung cancer, only 7% of female lung cancer patients in Taiwan have a history of cigarette smoking, extremely lower than those in Caucasian females. This report is a comprehensive analysis of the molecular signature of non-smoking female lung cancer in Taiwan.
