FG syndrome is an X-linked incomplete recessive condition comprising mental retardation, congenital hypotonia, macrocephaly, a distinctive facial appearance, and constipation or anal malformations. Here, we report on a chromosome X inversion [inv(X)(q12q28)] in a boy with FG syndrome and in his mentally retarded maternal uncle, and we discuss the possible involvement of this paracentric inversion in the FG syndrome.
