Opitz-Kaveggia syndrome (also known as FG syndrome) is an X-linked disorder
characterized by mental retardation, relative macrocephaly, hypotonia and constipation. We
report here that the original family for whom the condition is named and five other families
have a recurrent mutation (2881C> T, leading to R961W) in MED12 (also called TRAP230
or HOPA), a gene located at Xq13 that functions as a thyroid receptor–associated protein in
the Mediator complex.
