Question

A multifactorial disorder for which the genetic component is thought to be involvement of the HLA (human leukocyte antigen) type II genes and the environmental component is hypothesized to be infection with a virus is which one of the following?

(A) cancer
(B) diabetes Type 1
(C) diabetes Type 2
(D) hypertension

Answer 1

Diabetes Type 1, which is an autoimmune multifactorial disorder, involving genetic components related to HLA type II genes and environmental factors like viral infections, causes damage to pancreatic B cells resulting in insulin deficiency.

Step-by-step explanation:

The correct answer to the question is B) diabetes Type 1. Diabetes Type 1 is a multifactorial disorder with a significant genetic component linked to HLA (human leukocyte antigen) type II genes. Environmental factors, particularly viral infections, are also hypothesized to play a role in the development of this autoimmune disease. The immune system's targeting of pancreatic B cells, which produce insulin, is a characteristic aspect of Type 1 diabetes, leading to the lack of insulin production and subsequent dysregulation of blood glucose levels.
