Turner syndrome (TS), commonly known as 45,X, or 45,X0, [note 1] is a chromosomal disorder in which female cells have only one X chromosome instead of two, 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.
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 ...
Turner syndrome is a condition in females in which there is partial or complete loss of one X chromosome. This causes symptoms such as growth and sexual development problems. In 15% of Turner syndrome patients, the structural abnormality is isochromosome X, which is composed of two copies of the q arm (i(Xq)).
Parsonage–Turner syndrome, also known as acute brachial neuropathy, neuralgic amyotrophy and abbreviated PTS, is a syndrome of unknown cause; although many specific risk factors have been identified (such as; post-operative, post-infectious, post-traumatic or post-vaccination). [4]
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
While some infections it causes — like impetigo, strep throat and scarlet fever — are treatable, it can also lead to cellulitis, necrotizing fasciitis and streptococcal toxic shock syndrome.
[citation needed] An example of trisomy in humans is Down syndrome, which is a developmental disorder caused by an extra copy of chromosome 21; the disorder is therefore also called "trisomy 21". [7] An example of monosomy in humans is Turner syndrome, where the individual is born with only one sex chromosome, an X. [8]
Amy Schumer says she wouldn’t have known she had Cushing syndrome if it weren’t for Internet trolls. “A year ago, the Internet really came for me,” Schumer, 43, told Alex Cooper on the Jan ...
