Question

The most common reason a physician might recommend that a woman have maternal serum screening and a karyotype analysis is concern that her fetus may have Down syndrome. Go to the OMIM website at www.ncbi.nlm.nih.gov/omim and look up Down syndrome (OMIM 190685).

Summarize what is known about the location and genes found within the DSCR.

Accepted Answer

Hello, everyone and welcome to today's video. So what is the location and the example of genes found within the Down Syndrome chromosome region? As answer choice A, we have chromosome 13 and A P P and P S E and one genes. As answer choice B, we have chromosome 15 and EU B E three A and G A B R B three genes. As answer choice C, we have chromosome 21 A P P and S O D one genes as answer choice D we have chromosome 22 F M R one and F M or two genes. Now remember from previous videos that Down Syndrome is going to arise from certain abnormalities in chromosome 21. The only answer choice that contains chromosome 21 here is answer choice C which is chromosome 21 A P P and S O D genes. So as it turns out chromosomes 13, 15 and 22 which are answer choices. A B and D are not typically associated with Down Syndrome. And also the Down Syndrome Treaty called region is going to be located in chromosome 21 as well and it is going to be including the A P P or the amyloid precursor protein N DS O D one or they're super oxide, these mutate one jeans, which is exactly what, what answer choice C is saving. So chromosome 21 A P P and S O D one genes is going to be the correct answer to our question. I really hope this video helped you and I hope to see you on the next one.
