β¦ Synopsis
A family with X-linked mental retardation and a marker X chromosome was ascertained by the presence of macro-orchidism in the three institutionalized probands. Verbal evaluation revealed a generalized language disability with commonly occurring articulation errors. The heterozygous females in this family exhibited some reduction in mental ability; the marker X chromosome was demonstrated in both sexes.
