What do we mean by inherited disease?

Inherited factors can have different roles. Some are enough to cause disease or create a very high chance for disease. These are often diseases causes by a single gene.

We want to know about any single-gene, inherited diseases in your family.

Examples of inherited (single gene) diseases:

  • Cystic fibrosis

  • Huntington disease

  • Marfan syndrome

  • Sickle cell anemia

  • Tay Sachs disease

  • Charcot-Marie-Tooth disease

  • Fragile X

  • Neurofibromatosis

  • Thalassemia

  • Muscular dystrophy

Other diseases have multiple inherited factors but other factors are also important. These other factors might be habits like smoking or overeating, or things like too much sun (UV) light. Sometimes these conditions are called multifactorial or polygenic. Here, we will call them "familial" because they run in families but occur for complex reasons.

Examples of familial (multifactorial) diseases:

  • diabetes

  • hypertension

  • thyroid disease

  • lupus

  • depression, anxiety, or other mood disorders
