Exam 1- Genes, Environment-lifestyle, And Common Diseases Flashcards
Congenital
Present at birth but not inherited
Present at birth but not inherited
Congenital
Variation is caused by combined effects of multiple genes
Polygenic
Not shared by both members of a twin pair
Discordant trait
Variation is caused by combined effects of multiple genes.
Occurrence can change greatly from one population to another.
Recurrence (empirical?) risk is higher if more than one family member is affected and if the disease is more severe in the proband.
Many factors that can be measured numerically (like BP and CAD)
Multifactorial
Shared by both members of a twin pair.
Concordant trait
Proportion of a population affected at a specific point in time.
Prevalence rate
Polygenic
Variation is caused by combined effects of multiple genes
Proband
An individual with who a pedigree begins
Identical twins
Monozygotic twins
If rates are high/ the same between monozygotic and dizygotic twins, genetics is less likely to play a role. If different, most likely genetically linked.
Concordance rates
Inherited and transmitted through the generations.
Genetically inherited disease
Common measure of the effect of a specific risk factor. Expressed as a ratio of the incidence rate among individuals exposed to a risk factor divided by the incidence of the disease among people not exposed.
Relative risk
An individual with who a pedigree begins
Proband
Discordant trait
Not shared by both members of a twin pair
