Human monosomy
Human conditions due to monosomy:
- Turner syndrome – People with Turner syndrome typically have one X chromosome instead of the usual two sex chromosomes. Turner syndrome is the only full monosomy that is seen in humans — all other cases of full monosomy are lethal and the individual will not survive development.
- Cri du chat syndrome – (French for "cry of the cat" after the distinctive noise by affected persons' malformed larynx) a partial monosomy caused by a deletion of the end of the short arm of chromosome 5
- 1p36 deletion syndrome – a partial monosomy caused by a deletion at the end of the short arm of chromosome 1
- 17q12 microdeletion syndrome - a partial monosomy caused by a deletion of part of the long arm of [[chromosome 17]
