There are 47 chromosomes, instead of the usual 46, giving a 47,XYY karyotype. [1] Treatment may include speech therapy or extra help with schoolwork, however outcomes are generally positive. [2] The condition occurs in about 1 in 1,000 male births. [1] Many people with the condition are unaware that they have it. [4]
Klinefelter syndrome (KS), also known as 47,XXY, is a chromosome anomaly where a male has an extra X chromosome. [10] These complications commonly include infertility and small, poorly functioning testicles (if present).
Though a 48-chromosome complement involving the autosomes would be unsurvivable, 48,XYYY and other high-level sex chromosome aneuploidies such as XXXY syndrome and tetrasomy X—or indeed 49-chromosome disorders such as pentasomy X—are survivable with relatively mild phenotypes due to the paucity of genes vital to basic development on the sex ...
XX male syndrome, also known as de la Chapelle syndrome, is a rare intersex condition in which an individual with a 46,XX karyotype develops a male phenotype. [2] Synonyms for XX male syndrome include 46,XX testicular difference of sex development (or 46,XX DSD) [3] [4] [5] [6]
48,XXYY syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People normally have 46 chromosomes in each cell. Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics. Females typically have two X chromosomes ...
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 they have it.
FOX Nation host Rachel Campos-Duffy, 47, confirms 9th baby was born with heart defect, Down syndrome ... Valentina was also born with an extra chromosome, which means she also has Downs syndrome ...
The result is a genetic condition in which a person has 47 chromosomes instead of the usual 46. During egg or sperm development the 21st chromosome does not separate during either the egg or sperm development. The result is a cell that has 24 chromosomes. This extra chromosome may cause problems with the manner in which the body and brain ...
