Turner syndrome occurs in between one in 2,000 [4] and one in 5,000 females at birth. [5] All regions of the world and cultures are affected about equally. [10] Generally people with Turner syndrome have a shorter life expectancy, mostly due to heart problems and diabetes. [7] American endocrinologist Henry Turner first described the condition ...
Almost all women with regular Turner syndrome are sterile, but those with 47,XXX cell lines are typically fertile. [29] Although women with trisomy X have lower IQs than the general population and women with Turner syndrome do not, intellectual disability does not appear to be more common in the mosaic than for non-mosaic Turner's.

It is a feature of Turner syndrome [1] (only found in girls) and Noonan syndrome, [2] as well as the rarer Klippel–Feil syndrome, [3] or Diamond–Blackfan anemia. [4]

While Turner syndrome has similarities with renal anomalies and developmental delay, Turner syndrome is only found in females and often expresses differently. In Turner syndrome, there is a lower incidence of developmental delays, left-sided heart defects are constant and the occurrence of renal abnormalities is much lower. [36] Other RASopathies
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
Turner syndrome is usually not diagnosed until a delayed onset of puberty with Müllerian structures found to be in infantile stage. [4] Physical phenotypic characteristics include short stature, dysmorphic features and lymphedema at birth. [23] Comorbidities include heart defects, vision and hearing problems, diabetes, and low thyroid hormone ...
46, XX male syndrome, also known as de la Chapelle syndrome In this list, the karyotype is summarized by the number of chromosomes, followed by the sex chromosomes present in each cell. (In the second and third cases the karyotype varies from cell to cell, while in the last three cases, the genotype is normal but the phenotype is not.)
