What is the difference between a genetic disorder and a chromosom…?
Chromosomal abnormality is a broader term, describing duplications, loss, gain etc, of a particular chromosome. More related to the structures in an ideogram. Genetic disorder is a much broader term that describes any chromosomal or genetic…
What genetic disorder results in protein abnormalities??
All genetic disorders affect the structure of proteins.
Are genetic defects associated with abnormalities of autosomes or…?
It can be both. Sickle cell disease, cystic fibrosis, and Huntington’s chorea are all autosomal genetic diseases; certain kinds of hemophilia or colorblindness are “bad” alleles on the X chromosome. If you’re thinking of chromosom…

what level is marfan syndrome?!?
Q: i’m doing a science project on genetic disorders. my disorder is Marfan syndrome. does anyone know what level it is? well jsut tell me this please: is marfan syndrome a result of a chromosomal abnormality or is it caused by a defective gene?THANK YOU! (:
A: It is caused by a defect in the gene. The problem is in the structure of fibrillin (protein). I once heard it explained where it should say Sam ate eggs but would come out Sama tee ggs, etc where the words or letters got mixed up. This is why there is variable presence and symptoms in people. Not everyone is tall & skinny. Most have aortic problems but not all. Some have problems at birth, as child and some not diagnosed until their children have been or have even died.Good luck on the project! There are many good support groups online that will give you help/answers besides NMF’s website marfan.org or the many, many other country or world associations.
i need an ending sentence to my conclusion on a genetic disorder, what should it be?
Q: Arrhythmogenic right ventricular dysplasia is a genetic disorder that causes the muscles in the right ventricular to turn to fat. It is a rare form of cariomyopathy causing irrefular heart beats and quite possibly cardiac arrest. ARVD was discovered in the late 1970’s in France. Some symptoms are having shortness of breath, swollen legs, ankles and feet, being incapable of doing regular activities without getting tired or heart failure. ARVD is usually inherited from one parent but it is possible to get mthe mutated gene by congenital abnormalities.and now i need the perfect ending sentence to my report! please help!!!
