Fragile X-linked mental retardation: the Martin-Bell syndrome

B W Richards et al. J Ment Defic Res. 1981 Dec.

Abstract

Seven members of the original family of sex-linked mental retardation reported by Martin and Bell in 1943 have been re-examined and five of them proved to carry a fragile X chromosome. Some also display the typical facial appearance associated with this anomaly, and some have macro-orchidism. It is proposed that the condition should be designated "The Martin-Bell syndrome."
