| Gelineau's syndrome | <neurology> A disorder of sleep associated with excessive daytime sleepiness, involuntary daytime sleep episodes, disturbed nocturnal sleep and cataplexy. Narcolepsy affects over 100,000 people in the United States and appears to have a genetic basis. Symptoms usually begin in the patients twenties. Treatment often includes the use of amphetamines and-or tricyclic antidepressants. (27 Sep 1997) |

| mandibulofacial dysotosis syndrome | A hereditary disorder occurring in two forms: the complete form (franceschetti's syndrome) is characterised by antimongoloid slant of the palpebral fissures, coloboma of the lower lid, micrognathia and hypoplasia of the zygomatic arches, and microtia. It is transmitted as an autosomal trait. The incomplete form (treacher collins syndrome) is characterised by the same anomalies in less pronounced degree. It occurs sporadically, but an autosomal dominant mode of transmission is suspected. (12 Dec 1998) |
| mandibulo-oculofacial syndrome | A syndrome of bony anomalies of the calvaria, face, and jaw, with brachygnathia, narrow curved nose, and multiple ocular defects including microphthalmia, microcornea, and cataract, often with alopecia overlying skull sutures, or alopecia areata and hypoplasia, or absence of eyebrows. The pattern of inheritance is undecided. Synonym: congenital sutural alopecia, Hallermann-Streiff syndrome, Hallermann-Streiff-Francois syndrome, mandibulo-oculofacial syndrome, oculomandibulodyscephaly, oculomandibulofacial syndrome, progeria with cataract, progeria with microphthalmia. (05 Mar 2000) |
| gender dysphoria syndrome | <syndrome> A syndrome in which an individual experiences marked personal stress due to feelings that despite having the genitalia and secondary sexual characteristics of one gender there is a sense of compatibility and greater belonging to the other gender class; one may undergo surgery to reconstruct anatomy to that of the other gender. (05 Mar 2000) |
| general adaptation syndrome | <syndrome> The sum of all non-specific systemic reactions of the body to long-continued exposure to systemic stress. (12 Dec 1998) |
| Raynaud's syndrome | <syndrome> Idiopathic paroxysmal bilateral cyanosis of the digits due to arterial and arteriolar contraction; caused by cold or emotion. See: Raynaud's phenomenon. Synonym: Raynaud's disease, symmetric asphyxia. (05 Mar 2000) |
| Maranon's syndrome | <syndrome> A syndrome characterised by ovarian insufficiency, scoliosis, and flat-feet. (05 Mar 2000) |
| paraneoplastic syndrome | <oncology, syndrome> A collection of symptoms or clinical signs that are found in patients that have malignant disease. By definition, the signs and symptoms are not produced by a direct effect of a tumour or its metastasis nor due to direct invasion, compression, metastasis, infection, nutritional deficiency or treatment of the underlying neoplasm. Paraneoplastic syndromes can arise from tumour produced biologically active polypeptides or proteins, autoimmunity or immune complex production and immune suppression, blockade of the normal effect of a hormone, the release of substances from tumour associated endothelium which are not normally released and finally unknown causes. The best characterised paraneoplastic syndrome is the syndrome of inappropriate ADH. (15 Dec 1997) |
| Marchiafava-Micheli syndrome | An infrequent disorder with insidious onset (usually in the third or fourth decade) and chronic course, characterised by episodes of haemolytic anaemia, haemoglobinuria (chiefly at night), pallor, icterus or bronzing of the skin, a moderate degree of splenomegaly, and sometimes hepatomegaly; red blood cells are usually macrocytic and vary considerably in size, but there is no evidence of spherocytosis, erythrophagocytosis, or abnormal leukocytes. The disorder is a result of an abnormality of the red cell membrane which makes the red cell unusually sensitive to lysis by complement. Synonym: Marchiafava-Micheli anaemia, Marchiafava-Micheli syndrome. (05 Mar 2000) |
| Marcus Gunn syndrome | <syndrome> An increase in the width of the eye lids during chewing, sometimes with a rhythmic elevation of the upper lid when the mouth is open and ptosis when the mouth is closed. Synonym: Gunn phenomenon, Gunn's syndrome, jaw-winking phenomenon, jaw-working reflex, Marcus Gunn phenomenon, Marcus Gunn syndrome. (05 Mar 2000) |
| Marfan's syndrome | <syndrome> A hereditary condition of the connective tissue. Symptoms and signs include tall lean body type, irregular or unsteady gait, long extremities (including fingers and toes), abnormal joint flexibility, flat feet, stooped shoulders, dislocation of the optic lens and aneurysms of the aorta. Affects 1 in 50,000 people. Probably a collagen fibril assembly disorder since it can be mimicked in mice by aminonitriles that interfere with crosslinking. Inheritance: autosomal dominant. (06 Oct 1997) |
| marfan syndrome | <radiology> Connective-tissue disorder: autosomal dominant, 15% sporadic, cardiovascular system (probable cause of death in 93%), aortic aneurysm (mostly ascending), dilatation of aortic sinuses, aortic dissection, coarctation, musculoskeletal system, tall stature, long limbs, arachnodactyly, lax joints, scoliosis (60%) / kyphosis / pectus, eye, lens subluxation Cf: homocystinuria More info: Marfan syndrome (12 Dec 1998) |
| Marie-Robinson syndrome | <syndrome> Insomnia and mild melancholia associated with alimentary levulosuria. (05 Mar 2000) |
| Marinesco-Garland syndrome | <syndrome> A rare neurologic disorder characterised by cerebellolental degeneration with mental retardation; autosomal recessive inheritance. Synonym: cataract-oligophrenia syndrome, Marinesco-Sjogren syndrome, Torsten Sjogren's syndrome. (05 Mar 2000) |
| Marinesco-Sjogren syndrome | <syndrome> A rare neurologic disorder characterised by cerebellolental degeneration with mental retardation; autosomal recessive inheritance. Synonym: cataract-oligophrenia syndrome, Marinesco-Sjogren syndrome, Torsten Sjogren's syndrome. (05 Mar 2000) |
