The Fragile X Premutation

Traditionally, a carrier of a genetic condition is defined as a person who inherits an altered form of a gene but is asymptomatic or not at risk for nor has symptoms of the condition. However, in Fragile X this is different. Individuals with the Fragile X premutation may be at risk to develop Fragile X-associated conditions and disorders including Fragile X-associated tremor/ataxia syndrome (FXTAS) and Fragile X-associated primary ovarian insufficiency (FXPOI). Additional conditions associated with the Fragile X premutation are being further researched.

What Defines a Carrier?

By NFXF|2023-05-18T13:08:03-04:00Jun 26, 2013|

Why is there so much variability among male and female Fragile X carriers? There are a number of factors involved. Because the Fragile X gene is X-linked, gender plays a big role in determining who might show symptoms. Male premutation carriers, because they have only one X chromosome, are much more commonly affected by FXTAS than are female carriers.

FXAND: What Is It and What Might It Mean to You?

Research is currently underway looking at various issues that may be seen in people with the premutation.

Here we present a paper by Dr. Randi Hagerman, medical director and developmental pediatrician at the UC Davis MIND Institute in California, and well-known in the worldwide Fragile X community for her pioneering work in Fragile X syndrome (FXS) and Fragile X-associated tremor ataxia syndrome (FXTAS). For many years, Dr. Hagerman has believed that carriers of a Fragile X premutation are at risk for a variety of mental health and medical problems due to the premutation itself. This paper is one of her first attempts to describe what she and her colleagues believe to be the scientific basis for those problems.

General Anesthetic Use in Fragile X Spectrum Disorders

This is a topic we get a lot of questions about. This paper reports on two cases of premutation carriers with FXTAS who have experienced progression of their motor or cognitive problems after general anesthesia. Because of their molecular profile, it’s suggested that this group of patients may be at high risk for central nervous system dysfunction after anesthesia.
