Klinefelter's Syndrome. What is Klinefelter's Syndrome? Booklet on Klinefelter Syndrome Contact Group Klinefelter's syndrome is found in approximately 1 of 700 men, i.e. there are approximately 3600 boys and men with Klinefelter's syndrome in Denmark with 5 million inhabitants. Men usually have but one X and one Y chromosome, i.e. the chromosomeconstitution 46,XY. Men with Klinefelter's syndrome have more than one X chromosome, usually two X chromosomes, i.e. the chromosome constitution 47,XXY. At birth the testicles of Klinefelter boys are of normal size. When the testicles grow quickly in boys with normal chromosomes at the age of 11-12 years, the testicles of Klinefelter boys stay very small, as a rule only 2 cms. from pole to pole. Usually only few sperms are developed in the testicles, and men with Klinefelter's syndrome are as a rule infertile. Boys with Klinefelter's syndrome should be treated with testosterone, usually from the 11 or 12 years of age, best with Restandol tablets (Testosteroneundecanoat), which does not affect the liver, or with injections of other testosterone preparations. Klinefelter boys more often than other boys have delayed motor function, speech, and maturation development, which does not make them patients demanding special treatment. It is important that these boys at an early age go to a good day-care institution, and that there is a close cooperation between parents and day-care institution staff. If the speech development is delayed, it is important to get help from a speech-therapist for a period. Regarding the motor function development, the participation of parent/child in sports activities and group activities of any kind is of great value. The same is the case with regard to stimulating the delayed development in maturation. In this connection it must be mentioned, that it is also important to stimulate these boys to independence, and not in any way to overprotect them.

Diagnosis and Treatment of Klinefelter Syndrome CYNTHIA M. SMYTH University of Washington Many physicians underestimate the prevalence of Klinefelter syndrome and so fail to recognize its more obvious features. Increased awareness of its effects on physical, psychological, and social development should help to dispel persistent misconceptions about the condition and enable earlier diagnosis and more effective treatment. Dr. Smyth is in private practice and is also Clinical Instructor, Department of Internal Medicine, University of Washington, Seattle. Klinefelter syndrome is one of the most common causes of hypogonadism, affecting one in 500 men and boys. In two thirds of cases, the chromosomal karyotype is 47,XXY; in the remainder, variant and mosaic karyotypes predominate (Figure 1). Expression of the syndrome varies with the number of X chromosomes and the degree of endocrinologic dysfunction. The patient's history and physical examination provide enough information to diagnose the condition in puberty, but most patients do not seek medical attention until adulthood, when problems such as impotency or infertility become an issue. The following case is typical. Case Presentation A 44-year-old man presented to his primary care physician complaining of erectile dysfunction and infertility. Although he and his wife were able to have intercourse, they had been unable to have children. On questioning, he said that he was aware that he did not have the same libido as many of his friends. He had gone through puberty late and had not begun to shave until age 17. He had had academic, psychological, and social difficulties as a teenager and had been treated for depression as an adult. He had not had major medical problems such as high blood pressure or diabetes and did not drink or smoke.

In 1942, Harry Klinefelter, Fuller Albright, and their coworkers at the Massachusetts General Hospital published a report about 9 men who had enlarged breasts, sparse facial and body hair, small testes, and the inability to produce sperm. This combination of features has come to be recognized as Klinefelter syndrome. What causes Klinefelter syndrome? Klinefelter syndrome is caused by the presence of an extra sex chromosome. Males with the syndrome have a sex chromosome composition of XXY instead of the usual XY male sex chromosome complement. What is XXY? Chromosomes are carriers of DNA, the hereditary material. The chromosomes are visible under an ordinary light microscope. Men and women usually have 2 sex chromosomes. Women inherit 2 X chromosomes, one from each parent. Men inherit an X chromosome from their mother and a Y chromosome from their father.

Normally, men have an X and a Y and women have two X's. In Klinefelter syndrome, a male has two X's and a Y. The condition is common and affects 1 in 500 men. The infant appears normal at birth, but the defect usually becomes apparent in puberty when secondary sexual characteristics fail to develop (or develop late). At this time, testicular changes occur that eventually result in infertility in the majority of those affected. Some mild cases may go undetected, with no abnormalities present except infertility. One risk factor for this condition is the mother giving birth at an older age. In most cases, the problem develops during fetal development and is not inherited from one or both parents.

Normally humans have 23 pairs of chromosomes, the unfertilised ova and each sperm carrying a set of 23 chromosomes. On fertilisation the chromosomes combine to give a total of 46 (23 pairs). A normal female has an XX pair and a normal male an XY pair. The male affected by Klinefelter syndrome has two X chromosomes, as well as one Y, resulting in the formation XXY. A mosaic form also occurs where only a percentage of body cells contain XXY while the remainder carry XY. The extent of the affect will depend upon the proportion of XXY to XY throughout the body. There is an enormous variation in the expression of this condition. Some men are entirely normal and the diagnosis is only made for an incidental reason. It is important to give an open diagnosis to such children and not just paint a picture of the 'full blown' condition which is described below. It may be that just some of the features are present, such as tall stature or delayed puberty.

Home Bulletin Board (BBS) Chat Room Events ... Member Login Klinefelter Syndrome back to Medical Information Abnormalities of the sex chromosomes occur in about 1.5 per 1000 births, meaning that about 1200 children are born each year with one of these conditions. Turners syndrome, in which all or part of the X chromosome is missing, affects only girls, and is easily recognised, with short stature being an obvious symptom. At birth, infants are often smaller in respect of birthweight, length, and head circumference. During childhood, growth tends to be ahead of the child's peers, particularly in terms of leg length. Even by the age of three years leg length may be disproportionate to sitting height. In a clinical study of XXY boys, two thirds of the boys developed steadily increasing obesity, while the rest displayed lean and lanky stature. In three boys, who had high growth velocities, malposition of the testes was observed, with ascent of one testis occuring, requiring orchidopexy. Testicular development was normal up to the age of one year, apart from a reduction in the number of spermatogonia. Later, tubular diameter became reduced, and germ cells were not seen. Testicular volume increased in all boys at puberty, but this was followed by involution in those with the greatest development, resulting in a slight reduction in final volume.

UNDERSTANDING KLINEFELTER SYNDROME A GUIDE FOR XXY MALES AND THEIR FAMILIES Written by: Robert Bock Office of Research Reporting, NICHD NIH Pub. No. 93-3202 August 1993 CONTENTS What is Klinefelter Syndrome? Chromosomes and Klinefelter Syndrome Causes Diagnosis ... Resources WHAT IS KLINEFELTER SYNDROME? In 1942, Dr. Harry Klinefelter and his coworkers at the Massachusetts General Hospital in Boston published a report about nine men who had enlarged breasts, sparse facial and body hair, small testes, and an inability to produce sperm. By the late 1950s, researchers discovered that men with Klinefelter syndrome, as this group of symptoms came to be called, had an extra sex chromosome, XXY instead of the usual male arrangement, XY. (For a more complete explanation of the role this extra chromosome plays, see the accompanying section, "Chromosomes and Klinefelter syndrome." In the early 1970s, researchers around the world sought to identify males having the extra chromosome by screening large numbers of newborn babies. One of the largest of these studies, sponsored by the National Institute of Child Health and Human Development (NICHD), checked the chromosomes of more than 40,000 infants. Based on these studies, the XXY chromosome arrangement appears to be one of the most common genetic abnormalities known, occurring as frequently as 1 in 500 to 1 in 1,000 male births. Although the syndrome's cause, an extra sex chromosome, is widespread, the syndrome itself-the set of symptoms and characteristics that may result from having the extra chromosome-is uncommon. Many men live out their lives without ever even suspecting that they have an additional chromosome.
