    Notes: Abstract In an age when the majority of monogenic human disease genes have been identified, a particular challenge for the coming generation of human geneticists will be resolving complex polygenic and multifactorial diseases. The tools of molecular and population genetic association have much potential as well as peril in uncovering small cryptic genetic effects in disease. We have used a candidate gene approach to identify eight distinct human loci with alleles that in different ways influence the outcome of exposure to HIV-1, the AIDS virus. The successes in these gene hunts have validated the approach and illustrate the strengths and limitations of association analysis in an actual case history. The integration of genetic associations, well-described clinical cohorts, extensive basic research on AIDS pathogenesis, and functional interpretation of gene connections to disease offers a formula for detecting such genes in complex human genetic phenotypes.

    Notes: Abstract The compilation of a dense gene map and eventually a whole genome sequence (WGS) of the domestic cat holds considerable value for human genome annotation, for veterinary medicine, and for insight into the evolution of genome organization among mammals. Human association and veterinary studies of the cat, its domestic breeds, and its charismatic wild relatives of the family Felidae have rendered the species a powerful model for human hereditary diseases, for infectious disease agents, for adaptive evolutionary divergence, for conservation genetics, and for forensic applications. Here we review the advantages, rationale, and present strategy of a feline genome project, and we describe the disease models, comparative genomics, and biological applications posed by the full resolution of the cat's genome.

    Notes: Summary: The mammalian major histocompatibility complex (MHC) has taught both immunologists and evolutionary biologists a great deal about the patterns and processes that have led to immune defenses. Driven principally by human and mouse studies, comparative MHC projects among other mammalian species offer certain advantages in connecting MHC genome characters to natural situations. We have studied the MHC in the domestic cat and in several wild species of Felidae. Our observations affirm class I and class II homology with other mammalian orders, derivative gene duplications during the Felidae radiation, abundant persistent trans-species allele polymorphism, recombination-derived amino acid motifs, and inverted ratios of non-synonymous to silent substitutions in the MHC peptide-binding regions, consistent with overdominant selection in class I and II genes. MHC diversity as quantified in population studies is a powerful barometer of historic demographic reduction for several endangered species including cheetahs, Asiatic lions, Florida panthers and tigers. In two cases (Florida panther and cheetah), reduced MHC variation may be contributing to uniform population sensitivity to emerging infectious pathogens. The Felidae species, nearly all endangered and monitored for conservation concerns, have allowed a glimpse of species adaptation, mediated by MHC divergence, using comparative inferences drawn from human and mouse models.

    Notes: Abstract Genetic resistance to infectious diseases is likely to involve a complex array of immune-response and other genes with variants that impose subtle but significant consequences on gene expression or protein function. We have gained considerable insight into the genetic determinants of HIV-1 disease, and the HLA class I genes appear to be highly influential in this regard. Numerous reports have identified a role for HLA genotype in AIDS outcomes, implicating many HLA alleles in various aspects of HIV disease. Here we review the HLA associations with progression to AIDS that have been consistently affirmed and discuss the underlying mechanisms behind some of these associations based on functional studies of immune cell recognition.

    Notes: Advances in population and quantitative genomics, aided by the computational algorithms that employ genetic theory and practice, are now being applied to biological questions that surround free-ranging species not traditionally suitable for genetic enquiry. Here we review how applications of molecular genetic tools have been used to describe the natural history, present status, and future disposition of wild cat species. Insight into phylogenetic hierarchy, demographic contractions, geographic population substructure, behavioral ecology, and infectious diseases have revealed strategies for survival and adaptation of these fascinating predators. Conservation, stabilization, and management of the big cats are important areas that derive benefit from the genome resources expanded and applied to highly successful species, imperiled by an expanding human population.

    Notes: Abstract The polymorphisms within the human genome include several functional variants that cause debilitating inherited diseases. An elevated frequency of some of these deleterious mutations can be explained by a beneficial effect that confers a selective advantage owing to disease resistance in carriers of such mutations during an infectious disease outbreak. We here review plausible examples of balanced functional polymorphisms and their roles in the defense against pathogens. The genome organization of the chemokine receptor and HLA gene clusters and their influence on the HIV/AIDS epidemic provides compelling evidence for the interaction of infectious and genetic diseases in recent human history.

    Notes: [Auszug] African forest and savanna elephants are distinct species separated by a hybrid zone. Because hybridization can affect the systematic and conservation status of populations, we examined gene flow between forest and savanna elephants at 21 African locations. We detected cytonuclear dissociation, ...
