	XX gonadal dysgenesis - Wikipedia, the free encyclopedia
		XX gonadal dysgenesis is a type of female hypogonadism in which no functional ovaries are present to induce puberty in an otherwise normal girl whose karyotype is found to be 46, XX.
		The XX gonadal dysgenesis is the related to the Swyer syndrome inasmuch as both conditions have the same phenotype and clinical issues, however in Swyer syndrome the chromosome constellation is 46, XY, and thus requires gonadectomy.
		In Turner syndrome there is a demonstrable abnormality in or absence of one of the sex chromosomes that is the cause of the development of gonadal dysgenesis.

	Turner Syndrome: Encyclopedia of Children's Health
		Turner syndrome is a birth defect caused by the absence of an X chromosome in some or all cells of a female, which inhibits sexual development and usually causes infertility.
		Growth in children with Turner syndrome is characterized by a slight intrauterine growth retardation, relatively normal growth rates for the first several years of life, a progressive deceleration of growth later in childhood, and the lack of a pubertal growth spurt.
		Turner syndrome is either diagnosed at birth because of associated anomalies or at puberty when there is absent or delayed menses and delayed development of normal secondary sexual characteristics.

	Turner's Syndrome, Definition (Site not responding. Last check: 2007-10-24)
		Turner's Syndrome is a rare chromosomal disorder of females (1:2500) characterized by short stature and the lack of sexual development at puberty.
		In some cases of Turner's Syndrome, however, one X chromosome is missing from the cells (45,X); research studies suggest that approximately 40 percent of these individuals may have some Y chromosomal material in addition to the one X chromosome.
		Although the exact cause of Turner's Syndrome is not known, it is believed that the disorder may result from an error during the division (meiosis) of a parent's sex cells.

	Turner's Syndrome
		Turner's syndrome is a chromosomal abnormality involving absense of all or part of one X chromosome.
		Early in gestation the gonads appear normal and contain primordial germ cells, but after the third month, numbers become severely reduced and, in most patients oocytes are not present after birth.
		Turner's syndrome is commonly diagnosed prenatally, often in women undergoing amniocentesis or chorionic villus sampling for other reasons.

	Turner Syndrome - SJMMC, Ann Arbor, Michigan MI
		Turner syndrome is a rare chromosomal disorder of females characterized by short stature and the lack of sexual development at puberty.
		Turner syndrome occurs when one of the two X chromosomes normally found in women is missing or incomplete.
		Although the exact cause of Turner syndrome is not known, it appears to occur as a result of a random error during the division (meiosis) of sex cells.

	LYMPHEDEMA TURNER SYNDROME
		Turner syndrome is named after an American endocrinologist Dr Henry Turner who, in 1938 described seven women patients with similar physical features including short stature and the absence of female sexual characteristics, increased skin folds in the neck and a wide carrying angle of the arms.
		Turner syndrome occurs in females when one of the X (female) chromosomes is missing or damaged.
		In Turner syndrome, one of the X chromosomes is omitted or defective in the affected female.

	Medical Dictionary: Turner's syndrome - WrongDiagnosis.com
		Turner's syndrome: A syndrome in which the affected patients have only 45 chromosomes, the loss of one of the X chromosomes producing an XO chromosome constitution.
		Turner's syndrome : genetic disease that produces sterile females due to monosomy for X chromosome; the ovaries are rudimentary or missing; other abnormalities include short stature, webbed neck, and a broad chest with widely spaced nipples.
		Turner's syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).

	UNSW Embryology-OMIM GONADAL DYSGENESIS, XY FEMALE TYPE; GDXY
		Gonadal dysgenesis, XY female type, is associated with point mutations or deletions of the SRY gene (480000), but also in some cases with changes in the X chromosome.
		At birth the patients with the XY female type of gonadal dysgenesis (Swyer syndrome) appear to be normal females; however, they do not develop secondary sexual characteristics at puberty, do not menstruate, and have 'streak gonads.' They are chromatin negative and have a 46,XY karyotype.
		A high incidence of neoplasia (gonadoblastomas and germinomas) in streak gonads of patients with the XY karyotype was claimed by Taylor et al.

	Turner syndrome: Treatment with natural Estrogen
		Approximately one in 15 Turner girls is born with a stenosis (constriction) of the aorta (the main artery).
		Turner girls grow more slowly than other girls almost all through the growing period and this lack of height increase is the most common reason for parents of a girl with undetected Turner syndrome to contact a doctor.
		Turner women diagnosed too late, for instance at 18-20 years of age or later, are always very much in need of and very interested in getting full information, and in all such cases they express their deep regret and often some bitterness that they did not get this information and knowledge much earlier.

		Familial gonadal dysgenesis has an X-linked autosomal dominant inheritance and may be associated with campomelic dwarfism.
		These gonads may be separate or have elements of both type of gonad in a single organ.

	Turner Syndrome
		Turner Syndrome is a rare chromosomal disorder that occurs in females due to the absence of or defects in one X chromosome.
		Turner Syndrome is a rare disorder that affects only females and occurs in approximately 1 in 3,000 births in the United States.
		The diagnosis of Turner Syndrome is made by a blood test that examines the chromosomes under a microscope (karyotyping) and detects a missing or abnormal X chromosome.

		Her father's sister showed 46,XY female gonadal dysgenesis (Swyer's syndrome) as a result of a point mutation in the SRY gene on her Y chromosome.

		Mutations in this gene give rise to XY females with gonadal dysgenesis (one type of Swyer syndrome, 306100) and translocation of part of the Y chromosome containing this gene to the X chromosome in XX males (278850).
		In a patient with gonadal dysgenesis of the XY female type, Jager et al.
		The authors concluded that the previous report of a 46,XY patient with partial gonadal dysgenesis and the same mutation indicates the probable existence of a hotspot in this region of the SRY gene and strengthens the possibility that all gonadal dysgeneses constitute a spectrum of the same disorder.

		Studies of Turner Syndrome and its variants have contributed significantly to the understanding of SEX DIFFERENTIATION.
		This syndrome that was originally observed by Ullrich, and designated as identical to TURNER SYNDROME, related the webbing of the neck, loose skin and other anomalies of the syndrome to accumulation of fluid in the embryo starting at the head and dispersing to the extremities (as observed by Bonnevie in mice).
		Commonly observed at birth in Turner Syndrome and NOONAN SYNDROME; EDEMA of the extremities usually recedes by one year and is an early sign of Turner syndrome, especially in female neonates.

	biology - Endocrinology
		A neuroendocrine signal is a type of ‘classical’ hormone and is released into the bloodstream by a neurosecretory cell upon excited by a nervous signal.
		Peptide and Protein hormone are comprised of between three (in the case of thryotropin-releasing hormone (glutamic acid—histidine—proline)) and over 200 (in the case of follicle-stimulating hormone) amino acid residues and can have molecular weights as large as 30,000.
		Hormones mediate their effects by binding to specific and unique receptors in the target organ or organs, although the response following such recognition varies commensurate with the wide array of differing hormone functions.

		We are aware of the use of gonadectomy in Turner's Syndrome girls, but I don't think it applies to our son's case.
		Gonadoblastomas (type of testes cancer) are rare tumors in the general popula-tion but are associated with gonadal dysgenesis and, more specifically, the Y chromatin.
		Your son is probably also at risk of developing other types of testicular cancers.

		An intersex condition in which there appears some male structures (gonad, testis), as well as a uterus, vagina, and fallopian tubes.
		So even if the body makes the hormones needed to develop into a physical male, the body is unable to respond to those hormones, and therefore, a female body-type is the result even if the genetic sex is male.
		In some cases, laparoscopy, exploratory laparotomy, or biopsy of the gonads may be necessary to confirm disorders associated with ambiguous genitalia.
