The PAX-6 gene is a gene that translates to the PAX-6 protein that serves as a transcription factor needed to activate certain genes that functions in the development of the eyes. While PAX-6 gene may look like it produces different functions for different species (such as formation of the compound eye in insects vs. formation of a single lens eye in vertebrates), it does not. It does in fact only regulate the genes required for the formation of the eyes. Absence or mutation of the PAX-6 gene will cause aniridia or absence of the iris, opaque lens and cornea, and a dysfunctional retina. Also, the function of the PAX-6 protein is conserved throughout evolution of species.
Answer:
A fasting blood sugar test will be ordered.
Explanation:
A fasting blood sugar test or a glycated hemoglobin test is ordered in such situations. Additionally, tests to determine the insulin level as well as an ophthalmic investigation to determine diabetic retinopathy are ordered. Blood sugar level less than 100 mg/dl is classified as normal. A person is pre-disposed to diabetes if his blood sugar level is between 100-125 mg/dl.
A confirmed case of diabetes mellitus will have a fasting blood sugar level, 126 mg/dl and higher. Insulin administration and a proper management of diet are essential in managing the condition.
