  2. 26. Spatial Statistics and Ancestral Recombination Graphs with Applications in Gene Mapping and Geostatistics

    Author : Linda Werner Hartman; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetik; Genetics; cytogenetics; cytogenetik; genetic association analysis; ancestral recombination graph Generalized linear mixed models; kriging; bilinear interpolation; Gaussian Markov random fields; Statistics;

    Abstract : This thesis explores models and algorithms in geostatistics and gene mapping. The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. READ MORE

  4. 27. Linkage and association analysis in multiple sclerosis

    Author : Yamei Dai; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system, which is characterized by relapsing or progressive demyelinating plaques in the brain and spinal cord. It is well established that complex genetic factors influence susceptibility to MS. READ MORE

  5. 28. Novel Statistical Methods in Quantitative Genetics : Modeling Genetic Variance for Quantitative Trait Loci Mapping and Genomic Evaluation

    Author : Xia Shen; Örjan Carlborg; Lars Rönnegård; William Hill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; statistical genetics; quantitative trait loci; genome-wide association study; genomic selection; genetic variance; hierarchical generalized linear model; linear mixed model; random effect; heteroscedastic effects model; variance-controlling genes; Complex Systems – Microdata Analysis;

    Abstract : This thesis develops and evaluates statistical methods for different types of genetic analyses, including quantitative trait loci (QTL) analysis, genome-wide association study (GWAS), and genomic evaluation. The main contribution of the thesis is to provide novel insights in modeling genetic variance, especially via random effects models. READ MORE

  6. 29. Mapping Genes Affecting Phenotypic Traits in Chicken

    Author : Susanne Kerje; Leif Andersson; Martien Groenen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; chicken; Quantitative Trait Loci; growth; egg production; epistasis; plumage colour; Extended black; MC1R; Dominant white; PMEL17; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : The purpose of gene mapping is to understand the underlying genetics of simple and complex traits like plumage colour and growth. This thesis is based on a cross between the wild ancestor of the modern chicken, the red junglefowl, and a White Leghorn line selected for high egg mass. READ MORE

  7. 30. Hypospadias : gene mapping and candidate gene studied

    Author : Thi Thai Hanh Trinh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hypospadias is a common congenital malformation in boys, characterized by incomplete fusion of the urethral folds, abnormal opening of urethra and different degrees of curvature of the penis. In Sweden, the incidence of hypospadias is 1.14 per 300 male live-births according to the annual Swedish Malformation Registry. READ MORE
