Has prenatal genetic testing increased the detection rate of Duchenne muscular dystrophy (DMD), compared to prior diagnostic methods? If so, how? If not, why?
Homework Answers
Yes it is increased.
Prenatal diagnosis of DMD provides an option of pregnancy termination and an opportunity to deliver disease-positive infants at tertiary healthcare centers with a multidisciplinary approach.
Pregnancies at risk for DMD should be prenatally tested to prevent the effect of disease on families and DMD carrier fetuses had obstetric outcomes similar to DMD negative female fetuses.

Duchenne muscular dystrophy (DMD) is a disease that results in progressive muscle weakness, ultimately leading to paralysis. DMD is a genetic disease that is inherited in an X-linked recessive fashion. Two parents have a large number of children, and find that some of their children have DMD. Specifically, they find that none of their daughters have DMD, but half of their sons have DMD. a. What is the genotype the two parents? Please be sure to specify which genotype corresponds...

Duchenne muscular dystrophy (DMD) is a recessive X-linked disorder, which results in symptoms before the age of 6. A young girl, diagnosed with DMD has a 46 XX karyotype. The young girl’s brother is also living with DMD. Curiously, both parents are normal. Given the information in the question, why does this young girl have DMD? (1 sentence) How does this young girl have DMD? What mechanisms and how did this mechanism lead to this girl exhibiting DMD? (1 or...

A couple brought their child Tom (with DMD, Duchene Muscular Dystrophy) to test for the presence of the mutation (missing Exon 53) in his mother (carrier testing). They are seeking genetic counseling prior to planning their next child. Which molecular methodology is appropriate for carrier testing in this case? Present a schematic representation and explain the possible expected results for the mother.

3. In humans, Duchenne muscular dystrophy (DMD) is a disease where muscles become weaker over time. The gene is located on the X chromosome and is recessive. Those afflicted with this disease usually die in childhood. If a female is a carrier for DMD, what percentage of her sons will inherit the disease? What percentage of her daughters will inherit the disease? 4. Eye color in fruit flies is sex linked, with the recessive allele causing white eyes. Show the...

Dylan is a 36 year old female who has come for a routine 28 week prenatal check-up. She is a non-smoker, is physically active and has gained 4 kg of weight so far in her pregnancy. Dylan’s obstetrical history is G2 T0 P0 A1 L0. Both pregnancies have been assisted with in-vitro fertilization. During this first trimester, Dylan has suffered from nausea and vomiting but it has now resolved. Now, Dylan states she is exhausted all the time. The fetus is active and Dylan...
