Answer 1

When discussing future risks for the baby with the parents, you should inform them that their child has a higher risk of developing ________ due to the location on chromosome 21.

Answer: Alzheimers

Explanation:

The prenatal risk is assessed in women after screening to avoid the risk of the fetus. Chromosome 21 translocation cause a genetic defect of mental retardation(down syndrome) in newborn. Chromosome 21 is responsible for mental growth. At school age, it shows difficulty in communication and language. At an older age, it increases the risk of impaired cognitive function and more risk for developing Alzheimer's disease. The incidence rate shows 75% of people are at risk of early Alzheimer's disease. So the parents have to be discussed about this risk during prenatal screening and assessment.
