Fragile X, a recently discovered X-linked syndrome, is usually associated with mental retardation in affected males. Less consistent findings have been described for females. neuropsychological evaluation of seven nonretarded females from fragile X families suggested a characteristic profile: on Wechsler IQ tests, a positive Verbal-Performance score difference and lower subtest scaled scores on Arithmetic, Digit Span, Block Design, and Object Assembly; on the Wide Range Achievement Test, a lower score on Arithmetic than on Reading or Spelling; and on the Benton Visual Retention Test, defective recall. These results suggest the existence of X-linked learning disability in females.
