Fragile X syndrome: an overview and update of the FMR1 gene.

Fragile X syndrome: an overview and update of the FMR1 gene. Clin Genet. 2017 Jun 15;: Authors: Mila M, Alvarez-Mora MI, Madrigal I, Rodriguez-Revenga L Abstract Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and the leading form of the monogenic cause of autism. FMR1 premutation is the first single-gene cause of primary ovarian failure (FXPOI) and one of the most common causes of ataxia (FXTAS), multiple additional phenotypes such as fibromyalgia, hypothyroidism, migraine headaches, sleep disturbances, sleep apnea, restless legs syndrome, central pain syndrome, neuropathy and neuropsychiatric alterations has been described. Clinical involvement in men and women carrying the FMR1 premutation currently constitutes a real health problem in the society that should be taken into account. It is important to highlight that while in FXS there is a loss of function of the FMR1 gene, in premutation associated disorders there is a gain of FMR1 mRNA function. To date, the tremendous progress achieved in the understanding of the pathophysiology of FXS, has led to the development of several targeted therapies aimed at preventing or improving the neurological manifestations of the disease. This review is an update of the diseases associated with the FMR1 gene. PMID: 28617938 [PubMed - as supplied by publisher]
