Turner Syndrome
Introduction
Turner syndrome is a Overview of Sex Chromosome Abnormalities in which girls are born with one of their two X chromosomes partially or completely missing. Turner syndrome is caused by the deletion of part or all of one of the two X chromosomes. Girls with the syndrome are typically short and with loose skin on the back of the neck, learning disabilities, and an inability to undergo puberty. The diagnosis is confirmed by analyzing the chromosomes. Treatment with hormones can stimulate growth and initiate puberty. Chromosomes are structures within cells that contain The Sex chromosomes determine whether a fetus becomes male or female. A pair of X and Y chromosomes (XY) results in a male, and a pair of X and X chromosomes (XX) results in a female. Worldwide, Turner syndrome occurs in about 1 out of 2,500 live female births. Almost all affected fetuses miscarry spontaneously.
