This is the second of a series of three glossaries on genetic concepts used in epidemiological research that the journal is publishing with the objective of helping the reader "walk" around the journal.

Systemic lupus erythematosus is the prototype multisystem autoimmune disease. A strong genetic component of susceptibility to the disease is well established. Studies of murine models of systemic lupus erythematosus have shown complex genetic interactions that influence both susceptibility and phenotypic expression. These models strongly suggest that several defects in similar pathways, e.g. cl...

It is hard to believe that as recently as a decade ago, some of us were finding it virtually impossible to get an epidemiologic study funded from the National Cancer Institute if it required collection and analysis of DNA. Now, it is virtually impossible to get anything funded if you do not! The rapid transformation of epidemiology into the molecular world has been so swift and dramatic that by...

The most intriguing problems in genetics epidemiology are to predict genetic disease susceptibility and to associate single nucleotide polymorphisms (SNPs) with diseases. In such these studies, it is necessary to resolve the ambiguities in genetic data. The primary obstacle for ambiguity resolution is that the physical methods for separating two haplotypes from an individual genotype (phasing) ...

Respiratory diseases are major threats to human health. It is believed that chronic obstructive pulmonary disease (COPD) is both environmental and genetic ; however, specific genetic factors in the development of COPD have not been clearly identified, except for protease inhibitor types. Alpha1-antitrypsin deficiency is rare in the general population 5 and accounts for less than 2% of the cases...

PURPOSE OF REVIEW Osteoarthritis is the most common form of arthritis in the elderly and is influenced by both genetic and environmental risk factors. The scope of the present article is to offer an overview of recent developments in the genetic epidemiology of knee and hip osteoarthritis, with particular emphasis on published genomewide association studies (GWAS). RECENT FINDINGS Candidate g...

We have organized the Pancreatic Cancer Genetic Epidemiology (PACGENE) Consortium to identify susceptibility genes in familial pancreatic cancer (FPC). The Consortium comprises seven data collection centers, a statistical genetics core, and a pathology/archival genotyping core. We recruit kindreds containing two or more affected blood relatives ascertained through incident pancreatic adenocarci...

Epidemiological studies of multiple sclerosis have been performed on almost an industrial scale over the past 90 years. Morbidity statistics have been used to generate aetiological hypotheses, to assess local needs for the provision of services and the allocation of resources, and to define the natural history of the disease. Methodological factors have limited the extent to which the many surv...

results the highest prevalent genotype was genotype 4a, which was found in 57 patients (92%) followed by 2 isolates (3%) with genotype 4o, 2 strains (3%) with genotype 1g and one isolate (2%) with genotype 4n. conclusions this molecular epidemiology study revealed high prevalence of hcv genotype 4, subtype 4a among egyptian patients residing in sharkia governorate, egypt. patients and methods t...
