mental retardation (mr) is one of the most frequently found major genetic disorders around the world, affecting 1-3% of the people in the general population. the recent advancement in molecular biology and cytogenetic study has made possible the identification of new genes for a variety of genetic disorders including autosomal recessive mr. recessive genetic disorders are common in pakistan due...
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 ...
A genetic map of 31 biochemical loci located on 17 feline syntenic (linkage) groups has been derived by somatic cell genetic analysis of cat-rodent hybrids. Most of these syntenic groups have been assigned to one of the 19 feline chromosomes. Comparative linkage analysis of the feline biochemical loci and homologous human loci revealed considerable conservation of linkage associations between t...
This study reports QTL mapping for seed yield and its components in safflower genome under drought stress. The F3 families derived from the cross Mex.22-191 (tolerant) × IL.111 (sensitive) were evaluated for agronomic traits in safflower. Drought tolerance was evaluated during 10% of the flowering stage. To identify QTLs underlying tolerance to drought, mapping quantitative trait loci (QTLs) w...
The expected value of the squared linkage disequilibrium is derived for a neutral locus associated with a chromosomal arrangement that is maintained in the population by strong balancing selection. For a given value of recombination, the expected squared linkage disequilibrium is shown to decrease as the intensity of selection maintaining the arrangement increases. The transient behavior of the...
Genetic linkage analysis is a statistical method for mapping genes onto chromosomes, and is useful for detecting and predicting diseases. One of its current limitations is the computational complexity of the problems of interest. This research presents methods for mapping genetic linkage problems as Bayesian networks and then addresses novel techniques for making the problems more tractable. Th...
The approaches to identifying genes and genomic regions associated with human disease can be grouped into two categories: linkage analysis and genetic association analysis. Linkage analysis is useful for diseases of high penetrance that run strongly within families, but is limited in its ability to detect situations where there are multiple genes with smaller effects. An alternative is genetic ...
Linkage analysis is a tool used by geneticists for mapping diseasesusceptibility genes in the study of Mendelian and complex diseases. However analyses of large inbred pedigrees with extensive missing data are often beyond the capabilities of a single computer. We present a distributed system called SUPERLINK-ONLINE for computing multipoint LOD scores of large inbred pedigrees. It achieves high...
In genetic linkage studies, while the pedigrees are generally known, background relatedness between the founding individuals, assumed by definition to be unrelated, can seriously affect the results of the analysis. Likelihood approaches to relationship estimation from genetic marker data can all be expressed in terms of finding the most likely pedigree connecting the individuals of interest. Wh...
