Klinefelter syndrome typically causes a boy's testicles to grow at a slower rate than those of other boys. It also prevents the testicles from producing normal amounts of sperm and the hormone testosterone. Testosterone affects the way a boy develops both physically and sexually. Low hormone levels and problems with sperm production make it. Klinefelter's syndrome, XXY males, can occur due to nondisjunction of X chromosomes during prophase of meiosis I in females.

Diagnosis Doctors are able to diagnose Klinefelter syndrome during a pregnancy using a karyotype What is Klinefelter's Syndrome. Klinefelter's syndrome is a genetic disorder characterized by the presence of an additional X chromosome in almost all of the cells in the body. Thus, males with Klinefelter's syndrome have an XXY chromosome pattern. The symptoms of Klinefelter's syndrome are many, but not all the males show every symptom Klinefelter's syndrome is the most common genetic cause of human male infertility, but many cases remain undiagnosed because of substantial variation in clinical presentation and insufficient professional awareness of the syndrome itself. Early recognition and hormonal treatment of the disorder can substantially improve quality of life and prevent serious consequences

Klinefelter syndrome - Wikipedi

Klinefelter syndrome (XXY) 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. These are named either X or Y A karyotype is an organized profile of a person's chromosomes. In a karyotype, chromosomes are arranged and numbered by size, from largest to smallest. This arrangement helps scientists quickly identify chromosomal alterations that may result in a genetic disorder. To make a karyotype, scientists take a picture of someone's chromosomes, cut.

Difference Between Turner syndrome and Klinefelter syndrom

Ten percent to 20% of men with Klinefelter syndrome show a mosaic (mainly 46,XY/47,XXY) karyotype . Mosaic karyotypes arise from either nondisjunction in an early mitotic division of the developing (46,XY) zygote, or from loss of one of the X chromosomes of a 47,XXY conception (trisomy rescue) due to anaphase lagging 49,XXXXY syndrome is a type of chromosome abnormality characterized by the presence of 3 extra X chromosomes in males.

Dear Mr. and Mrs. Johnson, My name is Esai and I am a genetic counselor and my job is to advise individuals and familie The Klinefelter syndrome karyotype looks like this: 2. Edwards Syndrome. Edwards syndrome is also known as trisomy 18, because the baby has an extra chromosome 18 in all or some of their body cells. A few may also have translocated chromosomes. They are often born small and very frail, typically having many serious physical defects and health. Due to the extra chromosome individuals with this syndrome are referred as XXY males, or 47,XXY males. Klinefelter syndrome is named after Dr. Henry Klinefelter who first discovered the symptoms and discoveries found in males with an extra X. This chromosome constitution (karyotype) only appears in every one out 500 births Boys with Klinefelter syndrome may have difficulty with spelling, reading, writing, and paying attention. They may tend to be quiet, shy, and more reserved or sensitive than other guys. Some boys with Klinefelter syndrome are less interested in sports or physical activities Unlike the autosomes, monosomy for the Y chromosome is always lethal whereas monosomy for the X chromosome is a viable condition. The commonest syndromes that have ever been seen in the clinical setting are Turner syndrome, Klinefelter syndrome, Triple X syndrome and XYY syndrome (Smith et al., 1960). The karyotype of Klinefelter syndrome is 47.
