The purpose of this communication is to review the current status of phenotypic karyotypic correlations of human sex chromosomes. The data analyzed will include surveys of individuals with gonadal dysgenesis, 'Turner's syndrome,' primary amenorrhea, and sex chromosome anomalies, as well as isolated reports of individuals with more unusual rearrangements. In addition, the phenotypes associated with 45,X/46,XY mosaicism are discussed.
