Human BiologyGenetics
Quick Answer
The link between sex chromosome abnormalities and human disease emerged in the 1950s. Turner syndrome was described in 1938, but its chromosomal cause was identified later.
The Full Story
Human chromosomal disorders began to be understood clearly after the 1950s, when chromosome counting became accurate. Turner syndrome had been clinically described in 1938 by Henry Turner, but the underlying cause was linked to an X chromosome abnormality in 1959. That discovery helped launch modern medical genetics. It also showed that visible symptoms could be connected to precise chromosomal changes.
