What age does myotonic dystrophy affect?
Age at onset is between 20 and 70 years (typically onset occurs after age 40), and life expectancy is normal. The CTG repeat size is usually in the range of 50 to 150. Onset for DM2 ranges from the second to the seventh decade of life, often presenting with myotonia, weakness, or cataracts.
Is myotonic dystrophy more common in males or females?
Men and women are equally likely to pass on Myotonic Dystrophy to their children. Myotonic Dystrophy is a genetic disease and so can be inherited by the child of an affected parent if they receive the mutation in the DNA from the parent. The disease can be passed on and inherited equally by both sexes.
What part of the body does myotonic dystrophy affect?
Myotonic muscular dystrophy is a common multi-system disorder that affects the skeletal muscles (the muscles that move the limbs and trunk) as well as smooth muscles (the muscles that control the digestive system) and cardiac muscles of the heart.
Which is the most common medical condition inherited from the mother?
VWD is particularly problematic in women; it can cause excessive bleeding during menstruation for example, and lots during pregnancy. VWD is the most common bleeding disorder inherited by women in the U.S. This can be passed from mom to baby; your baby’s symptoms could be mild or as severe as yours.
Who are the next people to be tested for an abnormal gene?
If you test positive for an abnormal gene, the next people to be tested would be your siblings and/or your adult children. If any of them test positive, then they could have passed the mutation on to their own children. If they test negative, then they could not have passed on the mutation. These are just two possible scenarios.
What happens if my mother’s gene test is negative?
If her test is negative (no gene abnormality present), then you do not need to be tested, because she could not have passed the mutation on to you. If your mother’s test is positive, you might then decide to be tested. If your mother is no longer living, then you might go ahead with testing on the basis of your aunt’s test result.
Can a woman inherit breast cancer from her father?
“And women who inherit certain genetic mutations, such as those on the BRCA1 and BRCA2 genes, may have a lifetime risk of developing breast and/or ovarian cancer of anywhere from 50% to 85%. You can also inherit a genetic predisposition to breast cancer from your father’s side of the family.

What kind of health problems can you inherit from your mother?
Osteoporosis isn’t quite as strongly genetically linked as breast cancer can be, but there are family factors that put you at higher risk. Smaller-framed Asian and Caucasian women are at particular risk for osteoporosis. So if you inherited that body type from your mom, you need to take particular care of your bones.
How often do you inherit diseases from your parents?
If one of your parents has the mutated gene that causes this neurodegenerative disease, you have a 50% chance of inheriting that gene. If you do, you will develop Huntington’s 100% of the time. But most diseases that you might see in your mother (or your father) do not have nearly such a powerful genetic thumbprint.
