Henry Turner. Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic disorder in which females 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. [ 2 ][ 6 ][ 7 ] Most ...
approximately 1 in 1,000 (female) Trisomy X, also known as triple X syndrome and characterized by the karyotype [ note 1 ]47,XXX, is a chromosome disorder in which a female has an extra copy of the X chromosome. It is relatively common and occurs in 1 in 1,000 females, but is rarely diagnosed; fewer than 10% of those with the condition know ...
The Philadelphia chromosome or Philadelphia translocation (Ph) is a specific genetic abnormality in chromosome 22 of leukemia cancer cells (particularly chronic myeloid leukemia (CML) cells). This chromosome is defective and unusually short because of reciprocal translocation, t (9;22) (q34;q11), of genetic material between chromosome 9 and ...
Wilson-Turner syndrome (WTS), also known as mental retardation X linked syndromic 6 (MRXS6), and mental retardation X linked with gynecomastia and obesity is a congenital condition characterized by intellectual disability and associated with childhood-onset obesity. [1] It is found to be linked to the X chromosome and caused by a mutation in ...
The X chromosome is one of the two sex chromosomes in many organisms, including mammals, and is found in both males and females. It is a part of the XY sex-determination system and XO sex-determination system. The X chromosome was named for its unique properties by early researchers, which resulted in the naming of its counterpart Y chromosome ...
Familial adenomatous polyposis is a cancer syndrome in which there are hundreds to thousands of benign adenomas in the colon.. A hereditary cancer syndrome (familial/family cancer syndrome, inherited cancer syndrome, cancer predisposition syndrome, cancer syndrome, etc.) is a genetic disorder in which inherited genetic mutations in one or more genes predispose the affected individuals to the ...
46,XX/46,XY is either a chimeric or mosaic genetic condition characterized by the presence of some cells that express a 46,XX karyotype and some cells that express a 46,XY karyotype in a single human being. [1] [2] [3] While some individuals with this condition may be classified as intersex, others may have typical male or female characteristics.
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
