Dysesthetic Vulvodynia: Generalized pain in the vulvar region which can occur intermittently or constantly and has no obvious cause. The pain may be triggered by activities that put pressure on the area such as bike riding, tight clothes or even intercourse.
Dysferlinopathy (medical condition): An autosomal recessive form of limb-girdle muscular dystrophy where muscle weakness and atrophy is caused by deficiency of the dysferlin protein. There is variation in the degree of muscle involvement and the rate of progression.
Dysfibrinogenemia, familial is a type of familial medication condition that is not common. It is associated with an abnormal fibrinogen. Dysfibrinogenemia, familial involves several types and subtypes including Detroit, Wiesbaden, and Amsterdam dysfibrinogenemia.
Dysgerminoma: A rare form of cancer of the germ cells in the ovary. It is generally asymptomatic in the early stages. Prognosis with treatment is generally quite good.
Dysgnathia complex: A very rare disorder characterized by a small or absent jaw, ear abnormalities and a small mouth and tongue. The severity and range of symptoms is variable.
Dysharmonic skeletal maturation - muscular fiber disproportion: A very rare syndrome characterized mainly by abnormal bone development and muscle problems
Dyskeratosis congenita (DKC, Zinsser-Cole-Engman syndrome), is a rare progressive congenital disorder with a highly variable phenotype. The entity was classically defined by the triad of abnormal skin pigmentation, nail dystrophy, and leukoplakia of the oral mucosa, but these components do not always occur. DKC is characterized by short telomeres. Some of the manifestations resemble premature aging (similar to progeria). The disease initially mainly affects the skin, but a major consequence is progressive bone marrow failure which occurs in over 80%, causing early mortality.
Dyskeratosis congenita of Zinsser-Cole-Engman: An inherited condition characterized by recurring painful mouth ulcers, skin pigmentation and nail abnormalities.
Dyskinesia, drug induced: Dyskenisia (abnormal movements) caused by the use of certain drugs. The movements are involuntary and purposeless and can involve just about any part of the body e.g. lip puckering and rapid eye blinking. It can be caused by drugs such as neuroleptic drugs and other dopamine antagonists.
Dysmorphism - abnormal vocalization - mental retardation: A very rare syndrome characterized mainly by mental retardation, facial abnormalities and an abnormal voice.
Dysmorphism - cleft palate - loose skin: A very rare syndrome characterized mainly by facial abnormalities, an opening in the roof of the mouth and loose skin.
Dysmyelination (medical condition): Defective formation of or destruction of the myelin sheath around nerves
Dysosteosclerosis: A rare inherited condition characterized by bone development abnormalities (excessive hardening of bone and flattened vertebrae), characteristic facial features. Excessive bone growth at the base of the skull can damage the optic nerves and affect vision.
Dysostosis: Defective bone development. It can result in missing bones, extra bone, shortened bones or other bone abnormalities. Further symptoms depend on the type of abnormality.
Dysostosis acral with facial and genital abnormalities: A very rare inherited disorder characterized by short stature and head, face, skeletal and genital abnormalities. The facial appearance is that of a two-month old fetus. The severity and range of symptoms is variable. This dominantly inherited form of Robinow syndrome tends to be milder than the recessive form.
Dysostosis peripheral: A rare condition characterized by malformed bones in the hands and feet. The severity of the malformation is variable.
Dysostosis stanescu type (medical condition): A rare disorder involving abnormal bone and cartilage development.
An inherited form of dementia caused by nerve degeneration.
A speech disorder which sounds like stuttering and is caused by abnormal vocal cord movement.
A condition characterized by overgrowth of the epiphyseal cartilage on one of the hand or foot bones and occasionally on other bones.
A very rare syndrome characterized mainly by abnormal bone and brain development.
A skin condition characterized by numerous atypical nevi and moles which may develop into melanomas. The nevi and moles vary in size, shape and color and tend to develop during adolescence or young adulthood.
A rare disorder involving a deficiency of a protein (prothrombin or factor II) involved in blood clotting. The severity of symptoms vary according to the level of deficiency
A very rare syndrome characterized mainly by an abnormal opening in the lip and palate, forearm abnormalities, spinal cord defects and an abnormal abdominal opening allowing the abdominal contents to protrude.
A lethal syndrome characterized primarily by severe skeletal abnormalities.
A condition characterized by dwarfism, hydrocephalus, facial abnormalities and a narrow chest. The condition results in death during or soon after birth and is a more severe form of Rolland-Debuquois syndrome.
A condition characterized by dwarfism, hydrocephalus, facial abnormalities and a narrow chest. Survival is possible past infancy. The condition is a less severe form of Silverman-Handmaker syndrome which is lethal.
A very rare syndrome involving the early start of symptoms of dystonia and parkinsonism. The onset of the symptoms usually occurs suddenly over weeks or even hours and then progresses slowly.
Synonims: Rapid-onset dystonia-parkinsonism, DYT 12, RDB.
