"Fragi1e"meaning that chromosomes tend to break preferable at these sites.The X fragile site is now firmly established as being near the end of Xq. There is still some uncertainty whether the site is at band Xq27 or band Xq28 or at the interface of these 2 bands.The known fragile sites now include locations on chromosomes 2 , 6 , 7,9-12, 16, 20, and the X (Fig. 1).

At the start of this gene lies a region of DNA which varies in length from one person to another. Ordinarily, this stretch of DNA falls within a range of length that would be considered “normal”. 1. Int Rev Cytol. 1983;81:107-43.

Within the fragile X (FMR1) gene is a stretch of repeated trinucleotides with the sequence CGG. The nucleotides C and G are two of the four building blocks of DNA. Among people without the fragile X mutation, the number of these "CGG repeats" varies from 6 to about 40. The fragile X mutation involves an expanded number of the CGG repeats.

2021-04-07 Fragile X syndrome is a genetic disorder that occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should. Fragile X-associated Disorders are a family of inherited conditions caused by alterations (expansions) in the FMR1 gene (Fragile X gene) which is located on the X chromosome. These disorders include a wide range of physical, intellectual and behavioural symptoms that … An X-chromosome with a fragile site near the end of the long arm, resulting in the appearance of an almost detached fragment.

Fragile X Tremor/Ataxia syndrome (FXTAS) is a disease with the occurrence of progressive tremors and a decline in cognitive functions. 2018-10-10 Fragile X syndrome is caused by the expansion or lengthening of the FMR1 gene on the X chromosome, known as a gene mutation. The X chromosome is one of two sex-determining chromosomes. When the gene lengthens it switches off production of a protein that … From OMIM Fragile X syndrome is characterized by moderate to severe mental retardation, macroorchidism, and distinct facial features, including long face, large ears, and prominent jaw.

Fragile X syndrome is caused by a change in the fragile X mental retardation ( FMR1) gene. The FMR1 gene is located on the X chromosome.
