Acute Lymphoblastic/Lymphocytic Leukemia (ALL)Acute Lymphoblastic/Lymphocytic Leukemia (ALL) does not appear to be an inherited disease. It does not seem to run in families, so a person’s risk is not increased if a family member has the disease. But there are some genetic syndromes (some of which can be inherited from a parent) that seem to raise the risk of ALL.http://www.cancer.org/cancer/leukemia-acutelymphocyticallinadults/detailedguide/leukemia-acute-lymphocytic-risk-factors

ADD/ADHDThe genetic evidence for ADD/ADHD can be ignored but not argued away. Studies of twins and families make it clear that genetic factors are the major causes of ADD/ADHD.https://www.additudemag.com/with-evidence-that-adhd-is-genetic-mounting-should-testing-become-a-family-affair/

Agenesis of the Corpus Callosum (ACC)In most cases, it is not possible to know what caused an individual to have Agenesis of the Corpus Callosum (ACC) or another callosal disorder. However, research suggests that some possible causes may include chromosome errors, inherited genetic factors, prenatal infections or injuries, prenatal toxic exposures, structural blockage by cysts or other brain abnormalities, and metabolic disorders.https://en.wikipedia.org/wiki/Agenesis_of_the_corpus_callosum

Alagille SyndromeAlagille syndrome is an inherited condition in which bile builds up in the liver because there are too few bile ducts to drain the bile.

Amniotic Band SyndromeAlthough genetic factors are believed to play a role in the development of infants with some cases of amniotic band syndrome, the risk of recurrence in a subsequent child is extremely low.https://rarediseases.org/rare-diseases/amniotic-band-syndrome/
16
Antiphosphilipid SyndromeAntiphospholipid syndrome is a disorder characterized by an increased tendency to form abnormal blood clots (thromboses) that can block blood vessels. This clotting tendency is known as thrombophilia. In antiphospholipid syndrome, the thromboses can develop in nearly any blood vessel in the body. If a blood clot forms in the vessels in the brain, blood flow is impaired and can lead to stroke. Antiphospholipid syndrome is an autoimmune disorder. Most cases of antiphospholipid syndrome are sporadic, which means they occur in people with no history of the disorder in their family. Rarely, the condition has been reported to run in families; however, it does not have a clear pattern of inheritance. Multiple genetic and environmental factors likely play a part in determining the risk of developing antiphospholipid syndrome.https://medlineplus.gov/genetics/condition/antiphospholipid-syndrome/#frequency

Autoimmune (Hashimoto) ThyroiditisThe inheritance pattern of Hashimoto thyroiditis is unclear because many genetic and environmental factors appear to be involved.
