Turner syndrome happens when one of the X chromosomes is missing. The result in humans is a short female who may have some heart issues and may be sterile. At least according to the woman I know who has it.

As in men, the single X-chromosome doesn't deactivate.

I'm curious how single-X manifests in other mammals. And if Turner has autoimmune implications.

Based on your comment, it appears to me that there may be a correlation between the number of X or Y chromosomes and an individual's height. Typically, individuals possess either XX or XY chromosomes. However, variations such as XXY (Klinefelter syndrome) or XYY syndrome do exist and are associated with increased stature. The question of whether this correlation is scientifically substantiated and the mechanisms behind these phenotypic expressions are intriguing and worth exploring further.
