In the United States, most newborns undergo a test for primary congenital hypothyroidism, a condition where people are unable to produce enough thyroid hormone.Which of the following technologies can potentially facilitate the genetic screening of many newborns at higher efficiency and lower cost?
A)chorionic villus sampling.
B)whole-exome sequencing.
C)amniocentesis.
D)preimplantation genetic diagnosis.

Question

Quizplus · Accepted Answer

Whole-exome sequencing is a technology that can sequence all the protein-coding regions of the genome in one experiment. It allows for the detection of genetic mutations that cause conditions like primary congenital hypothyroidism through a single test. This technology has the potential to facilitate genetic screening of many newborns at higher efficiency and lower cost. Chorionic villus sampling, amniocentesis, and preimplantation genetic diagnosis are not appropriate for newborn genetic screening.
