Anorexia nervosa and ‘Turner syndrome’: cause or coincidence?

We report the eleventh documented case of the concurrence of anorexia nervosa and 'Turner syndrome'. Although some authors have suggested that the 2 syndromes occur together more often than by chance, and 5% of anorexia nervosa patients karyotyped to data have 'Turner syndrome', recent evidence in fact suggests that the 2 conditions do not occur together more often than one would expect by chance.
