Genetic Diseases are caused due to mutation inside one of the genes, deletion of any specific genes, chromosomal abberrations, abnormal extension of gene in its length. Unfortunately we don’t know ways to stop genetic disorders before giving birth to a child. Here is the list of the most common genetic disorders.

Angelman syndrome
Angelman Syndrome is a rare disorder, having neuro-genetic causes. The syndrom was first described in 1965 by Dr. Angelman. A syndrome is a based on group characteristics and manifest a specific condition. This syndrom can be described by an intellectual and evolutional delay, difficulty to speak, sleep problems, hand, laughter or just smiling and a happy appeareance.

Canavan disease
Canavan disease is a genetic disorder which produces gradual damage to nerve cells of the brain. This disease belongs to the category of genetic disorders named leukodystrophies. Leukodystrophies’ feature is myelin degeneration that is the phospholipid layer which protects nerve fibers.

Celiac disease
Celiac disease is a disorder which is autoimmune affecting the small bowel, which appears in the case of genetically predisposed persons belonging to all age categories, after first infancy stages. Its symptoms can be diarrhoea or fatigue, although these can be symptoms of other diseases too.
Celiac disease is produced by a reaction to gliadin, which is a gluten protein from wheat The lining of the small intestine will become flat, which prevents the absorption of nutrients. The unique efficient treatment is a permanent gluten-free diet.

Charcot-Marie-Tooth disease
Charcot-Marie-Tooth disease is a heterogeneous genetic disorder of nerves which is defined by touch sensation and loss of muscle tissue, especially in the legs and feet but in the arms and hands as well, in the advanced phases of disease. Even if for now it can’t be cured, this disorder is one of the most popular genetic neurological disorders. According to statistics, 36 in 100,000 are affected.

Color blindness
Color blindness, or deficiency to perceive colors can be of genetic nature, but can as well appear because of brain, eye, or nerve damage, or because of contact with some chemicals products. In 1798, the English chemist John Dalton studied for the first time this aspect, that is why it is sometimes called daltonism.

Cri du Chat
Cri du chat syndrome is a rare genetic disorder which affects an approximately 1 in 20,000 to 50,000 live births. The disease does not depend on ethnic backgrounds, but is most common in the case of women.

The disorder gets its name from the typical cry of babies born with this syndrom. The baby sounds like a kitten, because of problems with the nervous system and larynx. The good news is that about 1/3 of kids recover by the age of 2. Negative aspects of this disease may be:

1. Feeding problems because they can’t suck and swallow well
2. Low weight at birth and poor evolution,
3. Motor, cognitive, and speech delays,
4. Behavioral problems such as aggression, hyperactivity, and repetitive movements,
5. Uncommon facial traits that can change in time.

Cystic fibrosis
Cystic fibrosis is an inherited disorder which can affect the entire body, leading to gradual disability and death.
The most common symptoms are difficulty breathing and not enough enzyme production in the pancreas. Low immune system and dense mucous production lead to frequent lung infections, that are treated, but not always cured, sometimes by intravenous and oral antibiotics. Many other symptoms, like sinus infections, poor evolution, diarrhea can be effects of this disorder in the case of other parts of the body. Sometimes, recurrent lung infections during infancy or childhood may be a sign of cystic fibrosis.

Down syndrome
Down syndrome is a hereditary disorder which features problems related to cognitive ability, physical evolution, and facial traits. It is called after John Langdon Down, the doctor who described it in 1866, in Britain. Most of the times it is detected at birth.

Duchenne muscular dystrophy
Duchenne muscular dystrophy is a mortal disorder which is defined by rapidly gradual muscle weakness and damaged muscular tissue beginning in the pelvis and legs and then affecting the entire.

Hemophilia
Haemophilia is the name of some genetic disorders which mean the body's inability to control bleeding. The bleeding might be exterior, if the skin is broken by a cu
