Fragile X Syndrome The cause for Fragile X syndrome is mutation in one gene, the Fragile X Mental Retardation 1 gene, or the FMR1 gene. It is present on the X chromosome. This results in mental retardation. Mental retardation is further linked with more than five hundred different conditions.

Klinefelter's Syndrome Klinefelter's syndrome (KS) is a condition that occurs in men who have an extra X chromosome. The syndrome can affect different stages of physical, language, and social development. The most common symptom is infertility. Boys may be taller than other boys their age, with more fat around the belly.

X-linked disorder X-linked disorder. A condition in which the defective gene is on the X chromosome; because ♂ have one X chromosome, they are usually affected if the defective gene is structural–ie, necessary for function. See Autosomal dominant, Autosomal recessive.

- People with Fragile X syndrome also share certain medical problems as well as many common physical characteristics,2 such as large ears and a long face. In addition, having Fragile X is often associated with problems with sensation, emotion, and behavior.

Fragile X-associated Primary Ovarian Insufficiency (FXPOI) Fragile X syndrome, the most common heritable form of mental retardation in males, affects ~1/4000 males[1]. It occurs in most ethnic and racial populations, but incidence may vary from group to group[2]. Fragile X syndrome is an X-linked genetic disorder caused by a mutation in the FMR1 gene. Female carriers may pass it on to their children. Male children are expected to have the physical and behavioral features of the condition.

Fragile X Prevalence Approximately 1 million Americans carry the Fragile X mutation, including approximately 100,000 with Fragile X syndrome, and are at risk for developing a Fragile X-associated Disorder. Approximately 1 in 3,600 to 4,000 males in the world are born with the full mutation for Fragile X.

- Example-Fragile X: the most common form of mental retardation. The X chromosome of some people is unusually fragile at one tip-seen hanging by a thread under a microscope. Most people have 29 repeats at this end of their X-chromosome, those with Fragile X have over 700 repeats due to duplications.

Turner syndrome Turner syndrome is a chromosomal condition that affects development in females. The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is also very common.
