Linkage, case-control association, and family-based association tests for complex disorders

چکیده
We carried out an analysis of the Genetic Analysis Workshop 15 simulated Problem 3 data. We restricted ourselves to the present/absent phenotype. Linkage analysis revealed a very strong signal on chromosome 6. Association analysis revealed additional susceptible loci located on chromosomes 11 and 18. The latter two signals were subsequently verified with linkage analysis - but only after 20 replicates were pooled. Analysis of linkage disequilibrium patterns, in concert with family-based association tests, led us to infer the presence of a second chromosome 6 locus located in the vicinity of single-nucleotide polymorphisms 160-162. These analyses were carried out without knowledge of the model used to generate the simulation.

Association study of single nucleotide polymorphism rs165599 of COMT gene, with schizophrenia and bipolar mood disorder in the south-west of Iran
Linkage studies and epidemiological findings indicate that some possible genes in schizophrenia (SCZ) and bipolar mood disorder (BPD) are common. Numerous evidences for linkage of two diseases on chromosome 22 have been found. These findings suggest that one or more genes in the 22q11.21 region may be involved in the development of both disorders. In the present case-control study, association ...

متن کاملAssociation analysis of genetic polymorphisms in the CDC2 gene with late-onset Alzheimer disease.
BACKGROUND Alzheimer disease (AD) is a complex neurodegenerative disorder resulting from multiple genetic and non-genetic factors. Linkage studies indicated that chromosome 10 has at least one locus for this disease. The cell division cycle 2 (CDC2) gene, which is close to one of the linkage regions, has previously been associated with the risk of AD with an odds ratio of 1.78. Biologically, CD...
متن کاملA combined association test for rare variants using family and case-control data
Statistical association tests for rare variants can be classified as the burden approach and the sequence kernel association test (SKAT) approach. The burden and SKAT approaches, originally developed for case-control analysis, have also been extended to family-based tests. In the presence of both case-control and family data for a study, joint analysis for the combined data set can increase the...
متن کاملGene finding strategies.
Both linkage and association methods have been used to localise and identify genes related to behaviour and other complex traits. The linkage approach (parametric or non-parametric) can be used for whole genome screens to localise genes of unknown function. The parametric linkage approach is very effective for locating single-gene disorders and is usually based on large family pedigrees. The no...
