Everything You Should Know About Klinefelter Syndrome Klinefelter syndrome is a genetic disease that causes males to be born with an extra copy of the X chromosome in their cells. Males with this condition have smaller-than-normal testicles that produce less testosterone. Testosterone is the male hormone that stimulates sexual traits like body hair and muscle growth.

What Is Klinefelter Syndrome? Definition. Klinefelter syndrome is a genetic condition that results when a boy is born with an extra copy of the X chromosome. Klinefelter syndrome is a common genetic condition affecting males. Klinefelter syndrome adversely affects testicular growth, and this can result in smaller than normal testicles.

Alone we are rare. Together we are strong.â¥ Donate Today XYY syndrome is a rare chromosomal disorder caused by the presence of an extra Y chromosome. Normally, males have 46 chromosomes including one X and one Y chromosome. Males with XYY syndrome have 47 chromosomes, two of which are Y chromosomes.

Klinefelter syndrome Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. Two types of chromosome, called the sex chromosomes, determine the genetic sex of a baby.

- You're right that it just isn't having an X and a Y chromosome that makes a male (or that having two X's makes you a female). It is what our cells do with these chromosomes that makes a baby grow as a boy or a girl. Specifically, there is a gene on the Y chromosome called SRY that makes the big difference. This gene tells a baby to be a boy. Without the SRY gene, babies develop into girls. One way we know about this important gene is that there are some rare cases where someone has two X's but also has an SRY gene.

- Xyy redirects here. For the CIE XyY colour model, see XyY. XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births.

- Genetic sex is determined by the presence or absence of the Y chromosome. The Y chromosome determines the development of testes and maleness. The Y chromosome contains a sex determining region (the SRY gene), which encode the testis determining factor (TDF).

Dravet Syndrome Spectrum Dravet syndrome spectrum disorders are rare genetic epileptic encephalopathies (dysfunction of the brain) with onset during the first year of life in an otherwise healthy infant. There is a spectrum of severity ranging from no clinical symptoms, to simple febrile seizures, and extending to Dravet syndrome, which is the most severe. Mutations of the SCN1A gene cause 79% of diagnosed cases of Dravet syndrome.

Y chromosome The Y chromosome is one of two sex chromosomes in mammals, including humans, and many other animals. The other is the X chromosome. Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers testis development. The DNA in the human Y chromosome is composed of about 59 million base pairs. The Y chromosome is pass

- What determines maleness is the SRY region normally found on the Y chromosome. Basically, XX males and XY females can exist if that SRY region: 1. Is missing on the Y chromosome (in the case of the XY female) or 2. added onto an X chromosome (forming a XX male). This process is known as chromosome translocation.
