Monosomy is a form of aneuploidy with the presence of only one chromosome from a pair. Partial monosomy occurs when a portion of one chromosome in a pair is missing. Human monosomy
Human conditions due to monosomy:

Turner syndrome – People with Turner syndrome typically have one X chromosome instead of the usual two X 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 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

The newer term "generalised hypermobility spectrum disorder" includes people with generalised joint hypermobility, often determined using the Beighton Score, and other symptoms. Those who do not meet the Beighton Score criteria may be diagnosed with historical joint hypermobility spectrum disorder, peripheral hypermobility spectrum disorder, or localised hypermobility spectrum disorder.In comparison to the diagnostic criteria of hypermobile Ehlers-Danlos syndrome, the criteria for hypermobile spectrum disorder are less strict. However, these criteria are differentiated from criteria of other EDS types and therefore its less-strict criteria are only comparable to the criteria of hEDS. As those with HSD experience a considerable amount of discomfort, it is important to focus on the treatment, not the labels. The severity of each condition can be equivalent. In particular, musculoskeletal involvement is a requirement for diagnosis with any form of hypermobility spectrum disorder but not for hypermobile Ehlers-Danlos syndrome. Like hypermobile Ehlers-Danlos syndrome, hypermobility spectrum disorders are associated with orthostatic tachycardia, gastrointestinal disorders, and pelvic and bladder dysfunction. Treatment
Treating hypermobility syndrome can be difficult. The condition has no direct cure, but its symptoms can be treated. Physiotherapy, particularly exercise, is the main treatment for the condition, although there is only limited evidence for its effectiveness.Treatments for pain include:

Bandaging the affected area;
Placing an ice pack on the affected area;
Taking over the counter pain killers such as paracetamol or ibuprofen. Prevalence
Prevalence of the condition is unknown, but can be high in those attending musculoskeletal services. == References ==
