What is the function of the FMR1 gene?
A)Promoting brain development and maintaining neuronal synapses
B)Ensuring the expression of all other genes present on the X chromosome
C)Preventing amyloid plaque deposits and formation of neuronal tangles in the brain
D)Maintaining the structural integrity of the histone proteins surrounding the X chromosome

Question

Quizplus · Accepted Answer

The FMR1 gene, which is located on the X chromosome, codes for a protein that is critical in brain development and maintenance of neural synapses. If this protein is not produced in sufficient amounts or is abnormal, reduced cognition occurs, especially in males. FMX1 stands for fragile X mental retardation 1. Mutations are not responsible for the amyloid plaques and neuronal tangles that develop in Alzheimer's disease.
