Fragile X syndrome, is a genetic syndrome which results in a spectrum of characteristic physical, intellectual, emotional and behavioral features which include an elongated face, large or protruding ears, flat feet,
also known as Martin-Bell syndrome, Marker X syndrome, and FRAXA syndrome
The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.
Martin Bell Syndrome.
No, they are two different things. Normally, a woman has 46 X chromozomes. If there are only 45 of them, it´s the Monozomy X, so called Turner syndrome. If there are 47 of them, it´s the Trizomy X, also known as the Triple X syndrome.
No, fragile x syndrome is not progressive
X-linked
Turner syndrome or Ullrich-Turner syndrome.
No, Klinefelter syndrome and Turner syndrome are the result of nondisjunction of sex chromosomes. Klinefelter syndrome is caused by an extra X chromosome (XXY), while Turner syndrome is due to a missing X chromosome (XO).
X-inactivation typically occurs in individuals with Klinefelter syndrome, which is characterized by having an extra X chromosome (XXY). However, the extra X chromosome in Klinefelter syndrome may not undergo inactivation completely, leading to some cells expressing genes from the additional X chromosome. This can result in a variety of symptoms and characteristics associated with Klinefelter syndrome.
The three major chromosomal disorders are Down syndrome, Turner syndrome, and Klinefelter syndrome. Down syndrome is characterized by an extra copy of chromosome 21, Turner syndrome involves a missing or incomplete X chromosome in females, and Klinefelter syndrome is caused by an extra X chromosome in males.

There are 3 types of Turner syndrome Classic Turner syndrome - 45X - second X chromosome missing from all cells. Mosaic Turner syndrome - 45X/46XX - second X chromosome missing from some cells. The third type of Turner syndrome is when the second X chromosome is damaged or only partly missing.
