What gender is chromosome XXY?
A person’s biological sex is determined by the sex chromosomes: females have two X chromosomes, or XX; most males have one X chromosome and one Y chromosome, or XY. Males with XXY syndrome are born with cells that have an extra X chromosome, or XXY.
How many chromosomes are present in Klinefelter syndrome?
Most often, boys and men with Klinefelter syndrome have the usual X and Y chromosomes, plus one extra X chromosome, for a total of 47 chromosomes (47,XXY). Boys and men with Klinefelter syndrome have an extra copy of multiple genes on the X chromosome.
What is phenotype of XXY?
Introduction. Klinefelter syndrome (KS) (47,XXY) occurs in ∼1 in 650 males, and is associated with a physical phenotype that can include tall stature, hypogonadism, and fertility problems.

What Xxxxy 49?
49,XXXXY syndrome is a chromosomal condition in boys and men that causes intellectual disability, developmental delays, physical differences, and an inability to father biological children (infertility). Its signs and symptoms vary among affected individuals.
What karyotype is trisomy 21?
Trisomy 21, also known as Down syndrome, is a condition characterized by a distinctive pattern of minor and major anomalies associated with excess chromosome 21 material.
What is Klinefelter syndrome karyotype 47,XXY?
Klinefelter Syndrome (47, XXY) is a chromosomal variation in males in which one extra X chromosome is present, resulting in a 47,XXY karyotype. The extra X chromosome typically affects physical, neurodevelopmental, behavioral, and neurocognitive functioning.

Does standard karyotype diagnose Klinefelter?
The main tests used to diagnose Klinefelter syndrome are: Hormone testing. Blood or urine samples can reveal abnormal hormone levels that are a sign of Klinefelter syndrome. Chromosome analysis. Also called karyotype analysis, this test is used to confirm a diagnosis of Klinefelter syndrome.
What are the side effects of Klinefelter syndrome?
– 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. – Small, firm testicles. – Small penis. – Enlarged breast tissue (gynecomastia)
