Genetics and Heredity

  1. My wife believes that type 1 "goes sideways" genetically, that because her siblings have it, she is a carrier of the disease. Is this correct? (4 Jun 2016)
  2. In 2009, my daughter tested negative for antibodies, but recently had a high blood sugar and has tested positive for GAD-65. Will she definitely develop diabetes? (23 Jul 2015)
  3. What are the odds of having three kids in the same family with type 1? Are there known environmental triggers (causes)? (28 Feb 2012)
  4. My boyfriend has type 1. When we have children, will they have diabetes at birth? Is there a way to detect diabetes in utero? (20 Apr 2011)
  5. My daughter has had diabetes for 10 years. Since several of my family members are/have had complications, might there be some genetic component that my daughter will suffer them as well? (1 Feb 2011)
  6. I sometimes have elevated fasting blood sugars, but random readings in range. Is this normal? Should I discuss this with my doctor? (17 Jan 2011)
  7. My daughters are now the ages their brothers were when they were diagnosed. Negative for antibodies, so far, do they have a great risk of diabetes because both brothers have it? (15 Sep 2010)
  8. Both my husband and older son have type 1. Our infant son doesn't have the high risk genes. Is there still a higher probability than the general population that he might get type 1? (17 Mar 2010)
  9. My identical twin and I both have type 1. I have gastroparesis, while she has celiac. As twins, am I doomed to get celiac and is she doomed to get gastroparesis? (12 Oct 2009)
  10. Despite relative control of my type 1, I am worried about the future. Might any future children have diabetes, too? How can I prevent the fatigue I am experiencing? (19 Jan 2009)
  11. Two of my daughters were diagnosed with type 1 recently. A third had an A1c of 6.2, but is asymptomatic. Could she be in the early stages of diabetes? (22 Dec 2008)
  12. Because of the fragility of the Y chromosome, is a male fetus less likely then a female one to survive a diabetic pregnancy? (11 Dec 2008)
  13. Can the newborn baby of a hyperglycemic mother have hypoglycemia? What are the consequences for that baby? (12 Sep 2008)
  14. My one son was born with hypothyroidism. Another has type 1 and my husband has low testosterone levels. Are these conditions related/genetic? (24 Jun 2008)
  15. My niece has been complaining of tingling from her waist down. Should she be tested for a partial trisomy since there are genetic issues in our family? (11 May 2008)
  16. I read about a connection between blood glucose and likelihood of determining the sex of your unborn child. Does this mean type 1s are more likely to give birth to boys? (10 May 2008)
  17. Diagnosed last August, my teen son is unable to gain weight. What could be the problem? Should he have further tests? What are the risks for my older son? (3 Mar 2008)
  18. My girlfriend has type 1. What are the chances our children would have it, too? Is genetic mapping helpful for determining the chances that babies will have diabetes or not? (25 Feb 2008)
  19. Both my husband and his father have diabetes. Is there something I can do prior to conception or during my pregnancy to prevent our children from getting it? (28 Jan 2008)
  20. Our 11-year-old has had type 1 for seven years. Now, her younger sister has been diagnosed with it. Do my wife and I have certain genes that caused their diabetes? (7 Nov 2007)
