Studies done on large, extended families who have several family members affected with a rare disease are known as:
a. genetic association studies. c. kinships.
b. genetic epidemiology. d. phenotypes.
C
In genetic epidemiologic research of a rare disease, it can be a challenge to find enough people to study. One method is to work with large, extended families, known as kinships, which have several family members affected with the disease. Genetic association studies are usually conducted in large, unrelated groups based on demonstration of a phenotype (disease trait or symptoms) and associated genotype. Genetic epidemiology represents the fusion of epidemiologic studies and genetic and genomic research methods. Phenotypes are different at different stages of a disease and are influenced by medications, environmental factors, and gene–gene interaction.
