a genetic disease characterized by forty-five chromosomes with a sex chromosome count of X-; phenotypically female, but sterile.
Chromosome abnormality seen in about 1 in 3,000 live female births. It is marked by the absence of one sex chromosome. Characterized by short stature, primary amenorrhea and lack of development of secondary sex characteristics. Other features, which may or may not occur, include webbed neck, lowset ears, broad shield-like chest, hypertension, heart abnormalities and learning disorders. Treatment includes hormone therapy. See Amenorrhea; hypertension.
The most common chromosomal abnormality of mares, characterized by a missing X chromosome; also called 63,X gonadal dysgenesis.
a chromosomal disorder in females who have only one X chromosome; marked by dwarfism and heart abnormalities and underdeveloped sex organs
A congenital condition in which a woman has one less “X” chromosome rendering her infertile. Pregnancy can occur using an egg donor.
Rare chromosomal abnormality of the female. Turner's syndrome principally results in abnormal development of the ovaries and short stature. Women with this condition are sterile.
A sex-chromosome abnormality in man in which there is only a single X chromosome. Affected individuals are phenotypically female and usually have underdeveloped gonads.
A genetic disorder in women in which only one X chromosome is present, or both chromosomes are present but one is defective.
A genetic abnormality in females where a chromosome is missing, causing no ovarian function. close window
A congenital abnormality of the female wherein she receives an XO instead of an XX genetic sex complement. Women with this condition are sterile.
a genetic condition where the ovaries fail to fully develop and produce no eggs or very few eggs, resulting in total infertility. It occurs when one of the two X chromosomes is missing or incomplete.
CaF directory of specific conditions and rare syndromes A chromosomal condition affecting 1 in 2,500 girls where the second X chromosome is absent or abnormal. Turner's syndrome is generally characterised by short stature and non-functioning ovaries, usually leading to absence of pubertal development and infertility.
A rare, genetic disorder that affects females. Normal females have two X-chromosomes, whereas females with this syndrome typically have one. Common characteristics include short stature and failure to develop sexual traits during puberty.
A chromosomal abnormality of the woman in which one of the sex chromosomes are missing. this results is abnormal development of the ovaries. Such women are usually of short stature, infertile, and never menstruate.
The most common genetic defect contributing to female fertility problems. The ovaries fail to form and appear as slender threads of atrophic ovarian tissue, referred to as streak ovaries. Karyotyping will reveal that this woman has only one female (X) chromosome instead of two or a mosaic (46XX and 45X).
