Related QuestionsIS PMDD inherited?
facts for health--premenstual dysphoric disorder--frequently...Genetics may play a role in PMDD. Studies have shown that identical twins are more likely to share the disorder (93%) than non-identical (fraternal) twins (44%), and daughters of mothers with PMDD are more likely to have it themselves. However, no specific genes have been identified to account for PMDD. It is best to simply say that genetics may put a woman at greater risk for developing the disorder.

Related QuestionsIs alcoholism inherited?
Frequently Asked QuestionsResearch shows that the risk for developing alcoholism does indeed run in families. The genes a person inherits partially explain this pattern, but lifestyle is also a factor. Currently, researchers are working to discover the actual genes that put people at risk for alcoholism. Your friends, the amount of stress in your life, and how readily available alcohol is also are factors that may increase your risk for alcoholism. But remember: Risk is not destiny.
Related QuestionsIs ADHD inherited?
Duke ADHD Program – Frequently Asked QuestionsResearch shows that ADHD tends to run in families, so there are likely to be genetic influences. Children who have ADHD usually have at least one close relative who also has ADHD. And at least one–third of all fathers who had ADHD in their youth have children with ADHD. Even more convincing of a possible genetic link is that when one twin of an identical twin pair has the disorder, the other is likely to have it too.
Related QuestionsHow is PKD Inherited?
The Feline PKD FAQ -- Answers to Frequently Asked Questions ...In humans, there are two modes of inheritance: autosomal dominant and autosomal recessive (with at least two, and possibly three different autosomal dominant forms of PKD caused by different genes at different loci). To date, only the autosomal dominant form has been identified in cats.

Related QuestionsHow is RP inherited?
RP - Frequently Asked Questions (FAQ)Genetics is a complex subject, and The Foundation Fighting Blindness has prepared another booklet, "The Inheritance of Retinal Degenerations," to explain this topic in detail. (This can be ordered by using The Foundation's Publication Order Form.) There are so many different forms of RP, which fall within one of three standard inheritance patterns. Each type of inheritance will create a different pattern of affected and unaffected family members.
Related QuestionsIs PWS inherited?
QUESTIONS AND ANSWERS ON PRADER-WILLI SYNDROMEMost cases of PWS are attributed to a spontaneous genetic error that occurs at or near the time of conception for unknown reasons. In a very small percentage of cases (2 percent or less), a genetic mutation that does not affect the parent is passed on to the child, and in these families more than one child may be affected. A PWS-like disorder can also be acquired after birth if the hypothalamic portion of the brain is damaged through injury or surgery.

Is Down syndrome inherited?
Down Syndrome: FAQOnly 3 to 5% of cases are inherited; the rest arise as an accident of chromosome arrangement during meiosis. For details, see my essay on the origin of trisomy 21 or Dr. Paul Benke's essay on the types of DS, and the risk and recurrence risk of DS. No. Down syndrome occurs at conception, so nothing in the pregnancy can cause Down syndrome to occur. As for prior to conception, the research all shows that drug or alcohol use does not increase the risk of having a child with DS.

Related QuestionsIs hyperhidrosis always inherited?
Hyperhidrosis FAQNo. However in almost 50% of recorded cases there is a family history of hyperhidrosis. When a person is born with this condition he or she has primary hyperhidrosis while if hyperhidrosis develops as a result of another medical condition such as menopause or hyperthyroidism it is called secondary hyperhidrosis. In the latter instance the sweating is usually spread across larger areas of the body and not localized as in the case of primary hyperhidrosis as described in FAQ 1.
