X-Linked Alpha Thalassemia Family Support Network
X-Linked Mental Retardation Group
This group, headed by Richard Gibbons, has a particular
interest in a form of syndromal mental retardation known as X-Linked alpha
thalassemia mental retardation (ATR-X) syndrome. It is characterized by
severe learning difficulties, a characteristic facial appearance,
abnormalities of genital development including male pseudohermaphroditism
and alpha thalassemia. The underlying gene, ATRX, has been identified and
belongs to a sub-family of DNA-dependant ATPases and putative helicases.
Memebers of this family appear to be involved in a wide range of cellular
functions but a common thread is their ability to remodel chromatin.
The ATRX gene product is thought to be involved in the regulation of gene
expression since mutations give rise to alpha thalassemia via the down
regulation of alpha globin gene expression.
