Medical genetics: advances in brief: Rapid antibody test for fragile X syndrome

Genetic test for fragile X syndrome

Advances in research on the fragile X syndrome.

Fragile X syndrome is a neurodevelopmental disorder that results from a single gene mutation on the X chromosome. The purpose of this review is to summarize key advances made in understanding the fragile X premutation gene seen in carriers and the full mutation gene seen in persons with the syndrome. DNA testing has replaced cytogenetic testing as the primary method for identification of fragil...

Advances in understanding fragile X syndrome and related disorders.

PURPOSE OF REVIEW Fragile X syndrome is the most common form of inherited intellectual disability. Over the past 2 decades, insights into the cause of this disease have increased tremendously. This review will highlight recent discoveries with an emphasis on biochemical pathways affected in the disorder that are potentially amenable to treatment. RECENT FINDINGS Recent work in the field demon...

Advances in the treatment of fragile X syndrome.

The FMR1 mutations can cause a variety of disabilities, including cognitive deficits, attention-deficit/hyperactivity disorder, autism, and other socioemotional problems, in individuals with the full mutation form (fragile X syndrome) and distinct difficulties, including primary ovarian insufficiency, neuropathy and the fragile X-associated tremor/ataxia syndrome, in some older premutation carr...

Genetics of childhood disorders: XI. Fragile X syndrome.

Fragile X syndrome is a common form of mental retardation with an estimated incidence of 1 per 2,000 to 4,000 in the general population. The physical manifestations associated with the syndrome include macroorchidism, large ears, a prominent jaw, moderate to severe mental retardation, and autistic-like behavior. However, physical features are not always reliable indicators of the presence of th...
