Fragile X syndrome is a hereditary disease caused due to a surge in mental retardation 1 (FMR1) gene from chromosome X. This gene is responsible for encoding a particular protein is required for the development of the brain. Arm of chromosome with the mutated gene contains repetitive sequences (more than 200) of the same codon. In such a case, there is little or no production of the protein, which leads to symptoms of fragile X syndrome. The greater the number of repetitions, and severe syndrome. According to medical research, and this is the most common inherited mental disorder.
Interesting Facts about fragile X syndrome
Also turned to fragile X syndrome occurs in the chromosome associated with sex, this syndrome is more common among males than females. Since females two X chromosomes (XX), a child with FMR1 mutation in the X chromosome and one is a carrier of the syndrome, while girls with this mutation in each of the chromosomes (chromosomes) X suffers of fragile X syndrome. On the other hand, since males have X and Y chromosome, a boy with the FMR1 gene split from fragile X syndrome. It is estimated that one in every 4,000 males suffering from this syndrome of mental retardation.
Fragile X syndrome and hereditary and passed down from fathers to sons. Boy born to a mother and father normal carrier either suffer from this syndrome or not affected, while the girl born to the same parents is a carrier of the disease. In another case, the male suffering from this syndrome have sons and normal (derived X chromosome from the mother, but not the father) and his daughters carrier (as is the father passes on the X chromosome to his daughters all).
Symptoms of fragile X syndrome light at birth, and that thereafter. Sometimes, children who suffer from this syndrome are normal in infancy, but the development of typical characteristics later. Some physical properties manifested by individuals having fragile X syndrome and large prominent ears, elongated face with a prominent jaw, and extremely flexible joints and enlarged testicles.
Fragile X syndrome, a group of mental disorders such as hyperactivity, mental retardation, and a lack of interest, and intellectual disability, and duplication of activities and other emotional, social and behavioral problems. May be a symptom of learning difficulties ranging from mild to the problem of learning severe mental disorders. Other signs and symptoms include sensory abnormalities in behavior, social and emotional.
Are diagnosis of fragile X syndrome by chromosomal testing. Fragile X syndrome lifelong condition, and there is no cure. Treatment of this syndrome is aimed to improve the quality of life and symptom management. Along with medications, your doctor may recommend special education, speech or behavioral therapy for the management of symptoms.
To raise awareness about the fragile X syndrome results, individuals can not and having a family history of this syndrome opt for genetic counseling. And thus help to assess the likelihood of the presence of children who suffer from this syndrome. At present, and advanced technologies are also available to identify genetic abnormalities in the fetus. With understanding the underlying causes and current DNA research is still underway to detect positive treatments for fragile X syndrome
