Klinefelter's Syndrome: Causes & Symptoms Class 12 Biolog

  1. Klinefelter's syndrome is a sex chromosomal abnormality. It occurs due to the presence of an additional copy of X chromosome resulting in the karyotype of 47, XXY. The syndrome was named after American endocrinologist Harry Klinefelter's in 1942, who described about it. Klinefelter's syndrome occurs randomly
  2. Summary 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
  3. Klinefelter syndrome is a sex chromosome disorder in boys and men that results from the presence of an extra X chromosome in cells. People typically have 46 chromosomes in each cell, two of which are the sex chromosomes. Females have two X chromosomes (46,XX), and males have one X and one Y chromosome (46,XY). Most often, boys and men with Klinefelter syndrome have the usual X and Y.
  4. Patients with Klinefelter syndrome have a higher burden of psychiatric conditions, especially depression, anxiety, schizophrenia and psychosis, than the general population. 4,5,13,14 Adolescents are described as being sensitive, introspective and unassertive. 4,7,10 These characteristics may be related to feelings of insecurity about physique.
  5. Clinical Symptoms:Klinefelter's syndrome children are unusually tall for their age, have reduced facial and body hair, smaller testes, enlarged breasts and coarse voice (Fig. 8.2b and 8.3). Diagnosis and Treatment: One of the most frequent methods to diagnose Klinefelter syndrome is through Barr body test of buccal smear

Klinefelter syndrome is caused when a male baby is born with more than required or extra X chromosomes. This syndrome is found in 1 out of 1000 males. Klinefelter syndrome results in the formation of sperm or the egg and people with this syndrome are prone to tremors, osteoporosis and autoimmune disorders Following the 1st International Workshop on the Klinefelter Syndrome in 2010 (Juul et al., 2011), the 2nd IWKS took place in Münster, Germany from March 10 to 12, 2016 and was organized by the Centre of Reproductive Medicine and Andrology of the University of Münster.During the program, talks were presented by leading researchers in the field followed by lively discussions among the 120.

The condition is generally not inherited from a person's parents but rather occurs as a result of a random. Klinefelter syndrome (KS), also known as 47,XXY is a syndrome where a male has an additional copy of the X chromosome. The primary features are infertility and small, poorly functioning testicles. Often, symptoms are subtle and subjects do not realize they are affected. Sometimes, symptoms are more evident and may include weaker muscles, greater height, poor motor coordination, less body hair.

Klinefelter syndrome: MedlinePlus Genetic

Klinefelter's syndrome is due to trisomy of sex (X) chromosome. It is formed by the union of an abnormal XX egg and normal Y sperm or normal X egg and abnormal XY sperm. The individual has 47 chromosomes (44+XXY) Turner syndrome is the dysgenesis in the female gonads, while Klinefelter syndrome is the male hypogonadism. These can be explained by saying that both the terms are problems related to the sex chromosomes, as in the earlier one there is lacking of one of the sex chromosomes and so-called as monosomy (2n-1), while the latter consist of the extra sex chromosome and so-called as trisomy (2n+1) The 47,XXY karyotype of Klinefelter syndrome spontaneously arises when paired X chromosomes fail to separate (nondisjunction in stage I or II of meiosis, during oogenesis or spermatogenesis). [35] Maternal and paternal meiotic nondisjunction each account for approximately 50% of Klinefelter syndrome cases Klinefelter syndrome is defined as the male hypogonadism that occurs when there are two or more X chromosomes and two or more Y chromosomes.

About 20% of babies born with trisomy 13 survive the first year of life. It is difficult to predict the life expectancy of a baby with trisomy 13 if the baby does not have any immediate life-threatening problems. For babies that have survived their first 30 days of life, 47% were alive at one year - Because they still have the normal number of chromosomes. They are just arranged differently. - The danger is when both the robertsonian translocation (e.g. t(14q21q)) and one of the other non-translocated genes (e.g. 14 or 21) are inherited together (creates an aneuploidy as gametes only need one copy of any chromosome) in the pathological process of Klinefelter syndrome.
