| vitreo-tapetoretinal dystrophy | Autosomal recessive bilateral peripheral and central retinoschisis with pigmentary degeneration of the retina, chorioretinal atrophy, vitreous degeneration, and night blindness. Synonym: Favre's dystrophy. (05 Mar 2000) |
|---|---|
| Meesman dystrophy | Epithelial dystrophy characterised by progressive cysts and opacities of the corneal epithelium, with onset in infancy. Inheritance: autosomal dominant with incomplete penetrance. Synonym: Meesman dystrophy. (22 Sep 2002) |
| pelvofemoral muscular dystrophy | One of the less well-defined types of muscular dystrophy, probably heterogenous in nature. Onset usually in childhood or early adulthood and both sexes affected. Characterised by weakness and wasting, usually symmetrical, of the pelvic girdle muscles, the shoulder girdle muscles, or both, but not the facial muscles. Muscle pseudohypertrophy, heart involvement, and mental retardation are absent. Variable inheritance. Synonym: Leyden-Mobius muscular dystrophy, pelvofemoral muscular dystrophy, scapulohumeral muscular dystrophy. (05 Mar 2000) |
| vulvar dystrophy | A spectrum of vulvar eruptions consisting of white atrophic papules, including lichen sclerosus et atrophicus, squamous cell hyperplasia (hypertrophic dystrophy), or a combination of these (mixed dystrophy). See: lichen sclerosus et atrophicus. (05 Mar 2000) |
| reticular dystrophy of cornea | <ophthalmology> Bilateral, progressive, superficial degeneration of the corneal epithelium and adjacent Bowman's membrane. (05 Mar 2000) |
| childhood muscular dystrophy | The most common childhood muscular dystrophy, with onset usually before age 6. Characterised by symmetrical weakness and wasting of first the pelvic and crural muscles and then the pectoral and proximal upper extremity muscles; pseudohypertrophy of some muscles, especially the calf; heart involvement; sometimes mild mental retardation; progressive course and early death, usually in adolescence. X-linked inheritance (affects males and transmitted by females). Synonym: childhood muscular dystrophy, Duchenne's disease, pseudohypertrophic muscular dystrophy. (05 Mar 2000) |
| Groenouw's corneal dystrophy | A granular type of corneal dystrophy, with autosomal dominant inheritance, a macular type of corneal dystrophy, with autosomal recessive inheritance. (05 Mar 2000) |
| ring-like corneal dystrophy | Thread-like opacities of the anterior corneal stroma, with acute, painful onset followed by decreased vision; autosomal dominant inheritance. (05 Mar 2000) |
| gutter dystrophy of cornea | A marginal furrow usually inferiorly about 1 mm from the limbus; and sometimes bilateral. Synonym: keratoleptynsis. (05 Mar 2000) |
| microcystic epithelial dystrophy | Bilateral, symmetrical intraepithelial cysts in the central area of the cornea of healthy women, without hereditary predisposition. (05 Mar 2000) |
| mucopolysaccharide keratin dystrophy | A histologic finding seen in the surface epithelium of oral inflammatory fibrous hyperplasia, consisting of homogeneous eosinophilic pools of material in the superficial spinous layer. (05 Mar 2000) |
| cone dystrophy | A retinal abnormality in which colour perception is severely deficient and typical changes occur in electroretinogram. See: achromatopsia. Synonym: cone degeneration. (05 Mar 2000) |
| muscular dystrophy | A group of diseases characterised by progressive degeneration and/or loss of muscle fibres without nervous system involvement. All or nearly all of them have a hereditary origin but details of the type of genetic defect and of the prognosis for the disease vary from type to type. Duchenne muscular dystrophy (pseudohypertrophic muscular dystrophy) is the most common form. It is due to a sex-linked recessive allele and this is expressed as an absence of the protein dystrophin, the disease in boys shows extensive but insufficient muscle fibre reformation from satellite cells.

| corneal dystrophy | Central corneal opacification, usually bilateral, symmetrical, and often autosomal recessive, involving predominantly epithelial, stromal, or endothelial layers, often in a typical pattern. (05 Mar 2000) |
| myotonic dystrophy | <neurology> An inherited human neuromuscular disease classed as an autosomal dominant disease in which there is progressive muscle weakening and wasting. A triplet repeat syndromes (like fragile X syndrome), this most common adult form of muscular dystrophy is caused by expansion of the unstable trinucleotide repeat CTG in the 3' untranslated region on chromosome 19q13 (cAMP-dependent muscle protein kinase gene). Anticipation has been associated with further expansion of the repeat upon transmission to subsequent generations (the inheritance pattern is autosomal dominant), although contraction has been noted to occur as well. Especially severe neonatal cases have been born to affected mothers preferentially, suggesting a role for genomic imprinting as well. The classic physical signs include atrophy of facial muscles, cataracts, and delayed muscle relaxation. Detection of the expanded trinucleotide repeat is accomplished by PCR or Southern blot and expansion appears to correlate with decreased transcription of the protein kinase gene. Inheritance: autosomal dominant. (29 Dec 1997) |
