Fragile X

Fragile X syndrome is a genetic disorder that affects a person’s development, both in a person’s behavior and the ability learn.   Fragile X is an inherited disease in an X-linked dominant pattern.   Mutations in the FMR1 gene cause Fragile-X.   Not everyone with the mutated FMR1 gene has symptoms of the Fragile-X syndrome, because the body may still be able to make FMRP.  
Females with Fragile-X are not as severely affected by this disorder.   Most of the males with fragile X syndrome have mild to moderate intellectual disability, while about one-third of affected females are intellectually disabled.   Children with fragile X may have anxiety and hyperactive behavior such a fidgeting or impulsive actions.   Most have attention deficit disorder, which includes not having the ability to maintain attention, and the focus to stay on task.   One-third of individuals with fragile-x have autistic features that affect communication and social interaction.   Most males and about half of females with this disorder have characteristic physical features that are more distinguishable with age.   The features include long narrow face, prominent jaw a forehead, large ears, flat feet, unusually flexible fingers, and in males, enlarged testicles after puberty.
Fragile-X is an inherited disease in the X-linked dominant pattern.   The condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, which is one of the two sex chromosomes.   Women with the permutation have an increased risk of having a child with fragile X syndrome.   The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the disorder.   Females have two X chromosomes, so females are X-linked dominate.   In males who have only one X chromosome a mutation in the only copy of a gene in each cell causes the disorder.   In most cases females experience less severe symptoms than males.   Women with the permutation on the X chromosomes have an...
