Celiac disease is one of the most common genetic diseases affecting the digestive system. Celiac disease is common among individuals with gluten intolerance. Sufferers are unable to digest any type of food that contains gluten such as foods made from processed wheat or related grains. Celiac disease is very deadly when left undiagnosed since it causes malnutrition as well as dehydration because of symptoms like severe diarrhea. Other common signs/symptoms of celiac disease include digestive pain and abdominal bloating.
5. Noonan Syndrome
Noonan syndrome occurs when 1 of 4 chromosomes is affected. Noonan syndrome is a very common autosomal dominant congenital disease that affects both sexes equally. The disease affects one in every 2,500 children worldwide. It is passed onto children by both parents but tends to develop randomly shortly after birth. Children with Noonan syndrome don’t develop normally. They tend to have a small stature, wide-set eyes and distinct facial features like a flat bridged nose and a webbed neck.
6. Fragile X syndrome
Fragile X is another common genetic disease characterized by delayed development as well as mental retardation. Fragile X has some associations with autism. It occurs when part of the X chromosome is susceptible to breaking apart. The fragile area of the X chromosome may be repeated. Symptoms become more severe if there are many repeated areas on the X chromosome. Individuals suffering from Fragile X syndrome tend to have cognitive difficulties and developmental delays ranging from mild to severe. The disease is more prevalent in males than females i.e. it affects one in every 1,500 males and one in every 2,500 females.
