Linkage analysis of chromosome 2q in osteoarthritis.
BACKGROUND In independent linkage studies chromosome 2q11-q24 and chromosome 2q23-35 have previously been implicated as regions potentially harbouring susceptibility loci for osteoarthritis (OA). OBJECTIVE To test chromosome 2q for linkage to idiopathic osteoarthritis. METHODS Using a cohort of 481 OA families that each contained at least one affected sibling pair with severe end-stage dise...
متن کاملChromosome Inversions, Local Adaptation and Speciation.
We study the evolution of inversions that capture locally adapted alleles when two populations are exchanging migrants or hybridizing. By suppressing recombination between the loci, a new inversion can spread. Neither drift nor coadaptation between the alleles (epistasis) is needed, so this local adaptation mechanism may apply to a broader range of genetic and demographic situations than altern...
متن کاملHow and Why Chromosome Inversions Evolve
Alfred Sturtevant, who invented genetic mapping while still an undergraduate, published the first evidence of a chromosomal inversion in 1921 [1]. He suggested then, and later proved, that they have a dramatic effect on transmission: when heterozygous, inversions suppress recombination. Over the next half century, inspired largely by Dobzhansky and his coworkers, much of empirical population ge...
متن کاملTwo pericentric inversions of human chromosome 11.
A pericentric inv(11) (pl5q23) detectable by G-, Q-, and R-banding and occuring in 1 member of each of 3 generations of a family is described. In another family studied by several banding methods in search of chromosomal markers, a pericentric inv(11) (p11q11) was found. It was detectable only by C-banding, the darkly staining band being located on the short-arm side of the centromere. The reas...
متن کاملGenetic linkage analysis of chromosome 19 markers in malignant hyperthermia.
Previous studies have reported that malignant hyperthermia susceptibility is caused in some families by inherited variation in a gene located on the short arm of chromosome 19 near to, or identical with, the ryanodine receptor gene (RYR1); this is expressed in skeletal muscle as a calcium release channel of the sarcoplasm reticulum. In other families, a gene in this location is excluded, but th...
