Dr. Albornoz is a scientist researching the genetic variations of a particular gene among family members with a mood disorder. He intends to contrast these findings with a matched sample of families without the disorder. What method of study is Dr. Albornoz employing?

Question

Quizplus · Accepted Answer

Dr. Albornoz is comparing genetic variations between two groups - those with the mood disorder and those without. This aligns with the objective of an association study, which seeks to identify if a particular variant is more prevalent in cases (those with the disorder) compared to controls (those without the disorder). A linkage study, on the other hand, aims to identify the specific location of a disease-causing gene on a chromosome, whereas a longitudinal study follows a group of people over an extended period of time to study changes that may occur. A case study is an in-depth examination of a single individual, which is not the design Dr. Albornoz is using.
