Turner syndrome (TS), commonly known as 45,X, or 45,XO, [note 1] is a chromosomal disorder in which cells have only one X chromosome or are partially missing an X chromosome (sex chromosome monosomy) leading to the complete or partial deletion of the pseudoautosomal regions (PAR1, PAR2) in the affected X chromosome.
Ullrich congenital muscular dystrophy (UCMD) is a form of congenital muscular dystrophy.There are two forms: UCMD1 and UCMD2. [4]UCMD1 is associated with variants of type VI collagen, while UCMD2 is associated with variants of type XII collagen.
Henry Hubert Turner (August 28, 1892 – August 4, 1970) was an American endocrinologist, noted for his published description of Turner syndrome in 1938 at the annual meeting of the Association for the Study of Internal Secretions.
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.)
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 ] References

Archibald's sign appears to be more common in individuals who have Turners syndrome. It also seems to be more commonly found in pseudohypoparathyroidism of Albright's hereditary osteodystrophy, brachydactyly , acrodysostosis , and occasionally with homocystinuria .
Around 5% of females with Turner syndrome, defined by a karyotype with a single copy of the X chromosome, have a 47,XXX cell line. [14] Mosaic karyotypes with both 45,X and 47,XXX cells are considered Turner syndrome rather than trisomy X, but the presence of 47,XXX cells influences the disorder, [ 28 ] with milder effects than non-mosaic ...
