Description : Proud syndrome is an X-linked developmental disorder characterized by agenesis of
the corpus callosum, severe mental retardation, seizures, and spasticity. Males are
severely affected, whereas females may be unaffected or have a milder phenotype (Proud
et al., 1992). Proud syndrome is part of a phenotypic spectrum of disorders caused
by mutation in the ARX gene comprising a nearly continuous series of developmental
disorders ranging from lissencephaly (LISX2; 300215) to Proud syndrome to infantile
spasms without brain malformations (EIEE1; 308350) to syndromic (309510) and nonsyndromic
(300419) mental retardation (Kato et al., 2004; Wallerstein et al., 2008).;
Inheritance : X-linked;
Molecular basis : Caused by mutation in the X-linked aristaless-related homeobox gene (ARX, 300382.0015);
