Recent studies from Harvard University have found that only diseases classified as “monogenic diseases” are considered to be determinant factors of genetic diseases.

Monogenic genetic diseases are disorders caused by changes in the DNA sequence of a single gene. According to the Harvard University School of Medicine, all genes serve as patterns for different proteins to be produced and together provide the information necessary to structure the body and its functions. When a gene is abnormal, it can lead to a defective protein and in abnormal quantities, this can affect how the body functions.

It is important to keep in mind that inherited abnormal genes do not always have consequences on your health; sometimes the effects are minimal, but they can also lead to conditions that significantly decrease a person’s quality of life. According to Harvard, genetic diseases affect between 1% and 2% of the general population.

What are some of the most common genetic diseases?

  •        Cystic fibrosis
  •        Hemophilia A
  •        Spinal muscular atrophy
  •        Sickle-cell anemia
  •        Huntington’s disease
  •        Recessive autosomal recessive polycystic kidney disease
  •        Marfan syndrome

Also included in Harvard’s list of common diseases with strong genetic factors include migraines, celiac disease and different eye disorders such as glaucoma or cataracts; these conditions are not strictly linked to genetic inheritance, however.
