2. Any degenerative disease of gray matter in the central nervous system.
Radiographs show an abnormal thickness of bones, which is responsible for the fractures.
2. An autosomal recessive disease that affects bones and resembles osteopetrosis, but the disease is considered to be mild and not associated with hematological or neurological abnormalities.The only treatment is surgical correction of deformities and fractures.
2. Defective nutrition of hair, often culminating in alopecia. May be acquired or congenital; the latter often with metabolic or other birth defects.
This condition is associated with failure to thrive in life, physical and mental retardation, and progressive severe deterioration of the brain; apparently a defect of copper transport.
The sulfur content of the hair is greatly reduced and mental retardation has frequently been a related feature.
2. Congenital fragile hair with multiple fractures resulting from low sulfur-containing amino acid, cysteine, content of the hair, mental impairment, and short stature.2. A genetic disorder affecting women in which only one X-chromosome per cell is present, instead of two, resulting in underdeveloped ovaries and underdevelopment of the womb, vagina, and breasts.
Named after Henry Hubert Turner (1892–1970), an American endocrinologist; this congenital endocrine disorder, or ovarian dysgenesis, is caused by the failure of the ovaries to respond to pituitary hormone stimulation.
Clinically, a female with this endocrine disorder has a shorter than normal stature; absence of secondary sexual characteristics, with infantile development of the vagina, uterus, and breast; failure to develop sexual maturation, webbing of the neck, and inconsistent cardiac defects.
