Location of the FMR1 gene on the X chromosome. Fragile X syndrome is a genetic disorder which occurs as a result of a mutation of the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene on the X chromosome, most commonly an increase in the number of CGG trinucleotide repeats in the 5' untranslated region of FMR1.
FMR1 (Fragile X Messenger Ribonucleoprotein 1) is a human gene [5] that codes for a protein called fragile X messenger ribonucleoprotein, or FMRP. [6] This protein, most commonly found in the brain, is essential for normal cognitive development and female reproductive function.
While initially described as affecting male carriers, female carriers of the FMR1 gene mutation have also been found to develop FXTAS. However, due to X-inactivation, female carriers are much less likely to develop dementia or classic ataxia and tremor, instead demonstrating symptoms such as fibromyalgia, thyroid disease, hypertension, and ...
Fragile X-associated primary ovarian insufficiency (FXPOI) is the most common genetic cause of premature ovarian failure in women with a normal karyotype 46,XX. [1] The expansion of a CGG repeat in the 5' untranslated region of the FMR1 gene from the normal range of 5-45 repeats to the premutation range of 55-199 CGGs leads to risk of FXPOI for ovary-bearing individuals.

Silencing of the FMR1 gene in Fragile X syndrome. FMR1 co-localizes with a rare fragile site, visible here as a gap on the long arms of the X chromosome.. A chromosomal fragile site is a specific heritable point on a chromosome that tends to form a gap or constriction and may tend to break [1] when the cell is exposed to partial replication stress. [2]
Individuals with this syndrome have an abnormal expansion of these CGG repeats, leading to the silencing of the FMR1 gene and inhibiting FMRP protein production. This results in global developmental delays, communication disorders, intellectual disabilities and learning problems. [22]
This means oily fish and omega-3 supplements may improve heart health by reducing your risk of heart disease or cardiovascular disease while contributing to lower blood pressure.
This was the first to be identified as the underlying mutations in human genetic disorders. Their findings in FMR1 explained the unusual inheritance in Fragile X syndrome and provided the principles for all subsequent unstable repeat disorders such as myotonic dystrophy, Huntington's disease, and amyotrophic lateral sclerosis.
