    In many x-chromosome disorders such as Turner Syndrome, Prader-Willi Syndrome, etc., there is a growth hormone deficiency. Does anyone know where on the x chromosome the genes are located - the ones that cause the growth hormone deficiency? There seem to be autosomal causes of growth hormone deficiency as well, but I am interested in the ones that are on the x chromosome.

    Is there a Web Site that lists gene locations?

    Thanks.

    I tried Google and couldn't find it. All I found was some info about growth hormone deficiency on chromosome 17.

    However, when perusing research articles by Judith Ross I found the information.

    Two top results of google search:

    Turner syndrome or Ullrich-Turner syndrome (also known as "Gonadal dysgenesis"[1]:550) encompasses several conditions, of which monosomy X (absence of an entire sex chromosome) is most common. It is a chromosomal abnormality in which all or part of one of the sex chromosomes is absent (unaffected humans have 46 chromosomes, of which two are sex chromosomes). Typical females have two X chromosomes, but in Turner syndrome, one of those sex chromosomes is missing or has other abnormalities. In some cases, the chromosome is missing in some cells but not others, a condition referred to as mosaicism[2] or 'Turner mosaicism'.
    Turner syndrome (TS) is a medical disorder that affects about 1 in every 2,500 girls. Although researchers don't know exactly what causes Turner syndrome, they do know that it's the result of a problem with a girl's chromosomes (pronounced: krow-muh-soamz).

    Most girls are born with two X chromosomes, but girls with Turner syndrome are born with only one X chromosome or they are missing part of one X chromosome. The effects of the condition vary widely among girls with Turner syndrome. It all depends on how many of the body's cells are affected by the changes to the X chromosome.
