Mental Retardation, X-linked, Associated With Fragile Site Fraxe

Description

FRAXE mental retardation is a form of mild to moderate mental retardation associated with learning difficulties, communication deficits, attention problems, hyperactivity, and autistic behavior (summary by Bensaid et al., 2009). FRAXE is associated with a fragile site on chromosome Xq28 and is the cause of nonsyndromic X-linked mental retardation in 1 of 50,000 newborn males. The disorder can be caused either by silencing of the FMR2 gene as a consequence of a CCG expansion located upstream of this gene or by deletion within the gene (Stettner et al., 2011).
