Are Klinefelter Male Or Female?

What is the gender of YY?

The Y chromosome contains a “male-determining gene,” the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia.

If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes..

What race is affected by Klinefelter syndrome?

About 1 in every 500 to 800 males is born with this disorder; approximately 3000 affected boys are born each year in the United Sates. About 3% of the infertile male population have Klinefelter syndrome. The condition appears to affect all racial and ethnic groups equally.

Is Klinefelter syndrome more common in males or females?

Frequency. Klinefelter syndrome affects about 1 in 650 newborn boys. It is among the most common sex chromosome disorders, which are conditions caused by changes in the number of sex chromosomes (the X chromosome and the Y chromosome).

Can you be a girl with a XY chromosome?

The X and Y chromosomes are called “sex chromosomes” because they contribute to how a person’s sex develops. Most males have XY chromosomes and most women have XX chromosomes. But there are girls and women who have XY chromosomes. This can happen, for example, when a girl has androgen insensitivity syndrome.

What does a person with Klinefelter syndrome look like?

Taller than average stature. Longer legs, shorter torso and broader hips compared with other boys. Absent, delayed or incomplete puberty. After puberty, less muscle and less facial and body hair compared with other teens.

Is Klinefelter syndrome a disability?

Intellectual disability occurs in males with Klinefelter syndrome variants, who have a higher number of X chromosomes. About 70% of patients have minor developmental and learning disabilities.

What is the male version of Turner syndrome?

Consequently, in the past, Noonan syndrome has been referred to as “male Turner syndrome,” “female pseudo-Turner syndrome,” or “Turner phenotype with normal chromosomes karyotype.” However, there are many important differences between the two disorders.

Are XXY males infertile?

Main Points. Klinefelter syndrome (KS) is the most common chromosomal disorder in men and is associated with hypergonadotropic hypogonadism and infertility. Early hormonal therapy is recommended for patients with KS to assure normal puberty and prevent long-term consequences of hypogonadism.

What is Turner Klinefelter syndrome?

Turner syndrome (TS) is caused by having only one X chromosome (X0), and Klinefelter syndrome (KS) by having two X chromosomes and one Y chromosome (XXY).

Are there 2 genders?

There are more than two genders, even though in our society the genders that are most recognized are male and female (called the gender binary) and usually is based on someone’s anatomy (the genitals they were born with).

Is Klinefelter syndrome only in males?

Klinefelter syndrome (47,XXY) results from an additional X chromosome on an XY background; therefore, this condition affects only males.

How many sexes do humans have?

For biologically speaking, there are many gradations running from female to male; along that spectrum lie at least five sexes — perhaps even more. Medical investigators recognize the concept of the intersexual body.

Is there a female version of Klinefelter syndrome?

Objective: Numerical abnormalities of sex chromosome, 47,XXY karyotype, have the clinical phenotype of Klinefelter syndrome. Very few 47,XXY cases with a female phenotype have been reported. The testicular feminization syndrome is a female phenotype with a male karyotype (46,XY).

What is the life expectancy of a person with Klinefelter syndrome?

According to research, Klinefelter syndrome can shorten your life expectancy up to two years. However, you can still live a long, full life with this condition. The earlier you get treatment, the better your outlook will be.

Who is most likely to get Klinefelter syndrome?

Klinefelter syndrome results when a boy is born with at least 1 extra X chromosome. This is written as XXY. Klinefelter syndrome occurs in about 1 out of 500 to 1,000 baby boys. Women who get pregnant after age 35 are slightly more likely to have a boy with this syndrome than younger women.
