    At 7 months of age, a laparotomy was done, there was ambiguous genitalia at birth. At 14 1/2 years of age she had spontaneous pubertal development.
    Positive signals for Y were detected from blood, skin fibroblasts, and the left gonads but not in the right gonad.

    It was found that the fragile sites on various human chromosomes such as Xq27 or 28, 20p11, 2q1 and 10q23 were observed at a much greater frequency when medium 199 was used than when RPMI 1640, Ham''s F10, Eagle''s (basal), and CMRL 1969 were used.&It is suggested that the form of X-linked mental retardation with macro-orchidism and the form associated with the fragile site at Xq27 or 28 be the same entity.&On the basis of measurements made of the genital sizes it has been suggested that large and small size testes are features of the same X-linked form of mental retardation.
