In some cases, affected individuals may begin to undergo breast development and may begin menstruating without therapy spontaneous pubertal developmentbut most will stop developing sexually and stop menstruating at some later point during their teen-age years. Gastrointestinal problems including feeding difficulties and gastroesophageal reflux GERD may also occur.
Men have one X and one Y chromosome in their cells while females have two X chromosomes. Cause[ edit ] Turner syndrome is caused by the absence of one complete or partial copy of the X chromosome in some or all the cells. Kidney renal abnormalities may occur in some cases including horseshoe kidneys or absence agenesis of a kidney.
Turner syndrome may be diagnosed before birth or shortly after birth or during early childhood. Ear infections and hearing loss High waist-to-hip ratio the hips are not much bigger than the waist Attention deficit hyperactivity disorder problems with concentration, memory, attention with hyperactivity seen mostly in childhood and adolescence Nonverbal learning disability problems with maths, social skills, and spatial relations Other features may include a small lower jaw micrognathiacubitus valgus soft upturned nails, palmar crease, and drooping eyelids.

Common symptoms include short stature and premature ovarian failure, which can result in the failure to attain puberty. Genetic counseling may be of benefit for affected individuals and their families. In these cases, the loss of genetic material from the X chromosome usually occurs because of spontaneous errors very early during fetal development.
