Turner syndrome
  • Turner syndrome is a health complication that
    affects only girls and women when the X
    chromosome (a sex chromosome) is partially or
    completely missing. The syndrome can lead to
    developmental problems like short height, failure
    to start puberty, infertility, heart
    problems, learning issues and social behaviour
    problems. Turner syndrome is usually diagnosed
    in prenatal stages, during infancy or in early
    childhood. In some cases, the diagnosis is
    delayed till teen age because of mild signs and
    symptoms of the syndrome.

Causes of Turner syndrome
  • Most people are born with two sex chromosomes. A
    boy gets the X chromosome from his mother and the
    Y chromosome from his father. Similarly, a girl
    gets one X chromosome from each parent. If a girl
    has Turner syndrome, one X chromosome will be
    partially or fully absent. Symptoms of Turner
    syndrome includes 
  • The reason behind the absence of an X chromosome
    may be because of an error in the father's sperm
    or in the mother's egg. This results in every
    cell having only one X chromosome.
  • In certain cases, an error occurs in cell
    division during initial stages of foetal
    development. This results in some cells having
    two copies of the X chromosome. Other cells
    contain only one copy of the X chromosome.

Symptoms

    treatment

Treatments
  • Treatment for Turner syndrome involves hormone
    therapies for all girls and women 
  • In most of the cases, girls are
    recommended growth hormone therapy. The objective
    is to increase height as much as possible at
    right times during your daughter's childhood and
    teen years. Growth hormone treatment is given in
    the injection form several times a week. In
    addition, your doctor may recommend an androgen
    called oxandrolone.
  • Most girls with Turner syndrome require estrogen
    and similar hormone therapy to start puberty and
    achieve adult sexual development. Normally,
    Estrogen replacement therapy carries on for life
    until a woman reaches the average age
    of menopause.
  • Its difficult to distinguish the symptoms of
    Turner syndrome from other disorders. See your
    primary care physician if you believe your
    daughter shows signs of Turner syndrome.
