| aplasia cutis congenita | Congenital absence or deficiency of a localised area of skin, with the base of the defect covered by a thin translucent membrane; most often a single area near the vertex of the scalp, but may occur in other areas; underlying structures may also be affected; autosomal inheritance, either dominant or recessive. (05 Mar 2000) |

| aplasia | <embryology> A lack of development of an organ or tissue or of the cellular products from an organ or tissue. Compare: hypoplasia. Origin: Gr. Plassein = to form (18 Nov 1997) |

| radial aplasia-thrombocytopenia syndrome | <syndrome> Aplasia (absence) of the radius (the long bone on the thumb-side of the forearm) and thrombocytopenia (low blood platelets) are key features characterizing this syndrome. There is phocomelia (flipper-limb) with the thumbs always present. The fibula (the smaller bone in the lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the child affected with the disease. Alternative names include thrombocytopenia-absent radius syndrome, tar syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| germinal aplasia | A disorder in which the seminiferous tubules exhibit an abnormal cytoarchitecture and extensive hyalinization; the testes are small, and few spermatozoa are formed; the body habitus may be eunuchoid, and gynaecomastia may be present; urinary gonadotropin output is usually high, and the incidence of mental deficiency and illness increased; sex chromatin may be male or female, and androgen secretion ranges from subnormal to normal. It is a constant feature of (and is often used synonymously with) Klinefelter's syndrome. Synonym: germinal aplasia. (05 Mar 2000) |
| red-cell aplasia, pure | Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production. (12 Dec 1998) |
| gonadal aplasia | Congenital absence of essentially all gonadal tissue; the external genitalia and genital ducts are female, but if interstitial cells of Leydig are present, the external genitalia are commonly ambiguous and the genital ducts are female. See: gonadal dysgenesis. Compare: Klinefelter's syndrome, Turner's syndrome. Synonym: gonadal agenesis. (05 Mar 2000) |
| congenital aplasia of thymus | diGeorge syndrome |
| pure red cell aplasia | A transitory arrest of red blood cell production which may occur in the course of a haemolytic anaemia, often preceded by infection, or as a complication of certain drugs; if the arrest persists anaemia may result. See: congenital hypoplastic anaemia. (05 Mar 2000) |
| syndrome, radial aplasia-thrombocytopenia | See syndrome, tar. (12 Dec 1998) |
| thymic aplasia | <disease, immunology> A lack of T lymphocytes, due to failure of the thymus to develop, resulting in very reduced cell-mediated immunity though serum immunoglobulin levels may be normal. See: DiGeorge syndrome. Origin: Gr. Plassein = to form (18 Nov 1997) |
| amaurosis congenita of Leber | An autosomal recessive cone-rod abiotrophy causing blindness or severely reduced vision at birth. (05 Mar 2000) |
| amyoplasia congenita | Limitation of range of joint motion and contractures present at birth, usually involving multiple joints; a syndrome probably of diverse aetiology that may result from changes in spinal cord, muscle, or connective tissue. Several forms exist, autosomal dominant, recessive, and X-linked. Synonym: amyoplasia congenita. (05 Mar 2000) |
| amyotonia congenita | Atonic pseudoparalysis of congenital origin (neither familial nor hereditary), observed especially in infants and characterised by absences of muscular tone only in muscles innervated by the spinal nerves. Synonym: congenital atonic pseudoparalysis, myatonia congenita, Oppenheim's disease, Oppenheim's syndrome. An indefinite term for a number of congenital neuromuscular disorders that cause generalised myotonia in young children, and that have a benign course (static or regressive). (05 Mar 2000) |
| arthrogryposis multiplex congenita | Limitation of range of joint motion and contractures present at birth, usually involving multiple joints; a syndrome probably of diverse aetiology that may result from changes in spinal cord, muscle, or connective tissue. Several forms exist, autosomal dominant, recessive, and X-linked. Synonym: amyoplasia congenita. (05 Mar 2000) |
| pachyonychia congenita | A syndrome of ectodermal dysplasia of abnormal thickness and elevation of nail plates with palmar and plantar hyperkeratosis; the tongue is whitish and glazed owing to papillary atrophy; autosomal dominant inheritance. Synonym: Jadassohn-Lewandowski syndrome. (05 Mar 2000) |
| chondrodystrophia calcificans congenita | A developmental error of the epiphyses characterised by severe deformities, epiphyses ossified from several discrete centres and with a stippled appearance, and thickened shafts of the long bones; congenital cataract and mental retardation are often present. There is an autosomal dominant form and an autosomal recessive form. Synonym: chondrodysplasia punctata, chondrodystrophia calcificans congenita, hypoplastic foetal chondrodystrophy, stippled epiphysis. (05 Mar 2000) |
