The Editors thank the Virginia Commonwealth University Allergy/Immunology training program for developing this CME examination. The individuals who contributed to its preparation were Jigisha Morosky, MD, Jennifer Stribling, MD, and Lawrence B. Schwartz, MD, PhD.
Learning objectives: ‘‘Application of genetic/genomic approaches to allergic disorders’’ 1. To differentiate between the research methodologies currently used to study disorders that are at least in part heritable. 2. To increase awareness of current major international studies of inherited disorders. 3. To understand different types of genetic variation.

Question 7. SNPs occur at a rate of 1 SNP per how many base pairs of DNA? A. 100 B. 1,000 C. 10,000 D. 100,000
Question 9. Linkage analysis is a statistical approach to gene discovery that can be performed in — A. only family-based studies. B. only population-based studies. C. both population- and family-based studies. D. neither population- nor family-based studies.
Question 8. Aberrant DNA methylation of a 59-CpG island in the acyl-CoA synthetase long-chain family member (ACSL3) has been significantly associated with asthma risk in children born to mothers exposed to air pollutants. This is an example of which type of genetic variation? A. SNPs B. non-SNP variation C. copy number variation D. epigenetic reprogramming
Question 10. Association analysis detects disease-relevant genetic variation by determining whether — A. a genetic variant cosegregates with diseases in families. B. a genetic variant occurs more often in subjects with disease than in those without disease. C. particular regions of the genome at which inheriting DNA from ancestors from a certain region of the world predisposes one to a particular disease. D. combining information about known population history and information from a subject’s measured genotype can be used to localize disease genes.
