The importance of studying the generation of mutations in mouse germ cells is emphasized, and the utility of the biochemical specific-locus test in detecting germinal mutations is described. All experiments performed to date using this test are listed. The relevance of dominant mutations to human genetic risk is also discussed. Finally, the value of using multiple tests for the study of in vivo germinal mutations is discussed, and the design for a new multiple-endpoint system is presented.

Objectives: This study examined the utility of a family-based model for replicating the results of genome-wide association studies (GWAS) of type 2 diabetes (T2D).
Methods And Results: In a total of 232 members of a large consanguineous Omani Arab pedigree (age: 16-80years), there were 27 diabetics and 50 prediabetics (17 with impaired fasting glucose and 33 with impaired glucose tolerance). All 232 individuals underwent anthropometric and biochemical investigations and genotyped for 14 known common gene variants of modest effect on T2D risk.

Gametophytic self-incompatibility (GSI) is a mechanism in flowering plants, to prevent inbreeding and promote outcrossing. GSI is under the control of a specific locus, known as the S-locus, which contains at least two genes, the RNase and the SFB. Active S-RNases in the style are essential for rejection of haploid pollen, when the pollen S-allele matches one of two S-alleles of the diploid pistil.

Although a large percentage of the world population is seropositive for exposure to various strains of adeno-associated virus (AAV), a human parvovirus, AAV has never been identified as an etiologic agent of human disease. Most likely contributing to the pronounced lack of pathogenicity is the fact that AAV is a naturally defective virus that requires a helper virus for productive replication of its genome. Another unusual aspect of wild-type AAV biology is the ability of the virus to establish latent infection by preferential integration of its genome into a specific locus of human chromosome 19.

The sexual dimorphism of cardiovascular traits, as well as susceptibility to a variety of related diseases, has long been recognized, yet their sex-specific genomic determinants are largely unknown. We systematically assessed the sex-specific heritability and linkage of 539 hemodynamic, metabolic, anthropometric, and humoral traits in 120 French-Canadian families from the Saguenay-Lac-St-Jean region of Quebec, Canada. We performed multipoint linkage analysis using microsatellite markers followed by peak-wide linkage scan based on Affymetrix Human Mapping 50K Array Xba240 single nucleotide polymorphism genotypes in 3 settings, including the entire sample and then separately in men and women.

Parental exposure of mice to radiation and chemicals causes a variety of adverse effects (e.g., tumors, congenital malformations and embryonic deaths) in the progeny and the tumor-susceptibility phenotype is transmissible beyond the first post-radiation generation.
