anomaly /anom·a·ly/ (ah-nom´ah-le) marked deviation from normal, especially as a result of congenital or hereditary defects.anom´alous
Alder's anomaly an autosomal dominant condition in which leukocytes of the myelocytic series, and sometimes all leukocytes, contain coarse azurophilic granules. Chédiak-Higashi anomaly see under syndrome. congenital anomaly a developmental anomaly present at birth. developmental anomaly 1. a structural abnormality of any type. 2. a defect resulting from imperfect embryonic development. Ebstein's anomaly a malformation of the tricuspid valve, usually associated with an atrial septal defect. May-Hegglin anomaly an autosomal dominant disorder of blood cell morphology, characterized by RNA-containing cytoplasmic inclusions (similar to Döhle bodies) in granulocytes, by large, poorly granulated platelets, and by thrombocytopenia. Pelger's nuclear anomaly Pelger-Huët nuclear a. (1). Pelger-Huët nuclear anomaly
1. a hereditary or acquired defect in which the nuclei of neutrophils and eosinophils appear rodlike, spherical, or dumbbell-shaped; the nuclear structure is coarse and lumpy. 2. an acquired condition with similar features, occurring in certain anemias and leukemias.
developmental anomaly, any congenital defect that results from interference with the normal growth and differentiation of the fetus. Such defects can arise at any stage of embryonic development, vary greatly in type and severity, and are caused by a wide variety of determining factors, including genetic mutations, chromosomal aberrations, teratogenic agents, and environmental factors. Developmental anomalies are classified either according to the organ system affected, such as congenital heart defects, or according to the way in which the defect occurred, such as developmental failure or arrest, failure to atrophy or subdivide, fusion, splitting, incorrect migration, and misplacement. Most developmental defects are apparent at birth, especially any structural malformation, but some, especially those involving the organ systems, do not become evident until days, weeks, or even years later. anomaly [ah-nom´ah-le] marked deviation from normal. adj., adj anom´alous. Axenfeld's anomaly a developmental anomaly characterized by a circular opacity of the posterior peripheral cornea, and caused by an irregularly thickened, axially displaced Schwalbe's ring. congenital anomaly (developmental anomaly) absence, deformity, or excess of body parts as the result of faulty development of the embryo. Ebstein's anomaly see ebstein's anomaly. May-Hegglin anomaly a rare dominantly inherited disorder of blood cell morphology, characterized by RNA-containing cytoplasmic inclusions (similar to Döhle bodies) in granulocytes, by large, poorly granulated platelets, and by thrombocytopenia.
anomaly ( n an aberration or deviation from normal anatomic growth, development, or function. anomaly, dental, n an abnormality in which a tooth or teeth have deviated from normal in form, function, or position. anomaly, developmental n 1. an abnormality originating in fetal development. 2. deficiencies or imperfections occurring in the teeth as a consequence of irregular tooth growth. anomaly, dysgnathic n an older term for an abnormality that extends beyond the teeth and includes the maxillae, the mandible, or both. anomaly, eugnathic n an older term for an abnormality limited to the teeth and their immediate alveolar supports. anomaly, gestant n See odontoma. anomaly, maxillofacial, n a distortion of normal development of the face and jaws; a dysgnathic anomaly. anomaly, oral, n an abnormal structure of the oral cavity other than of the teeth. anomaly, orofacial, n a term indicating an oral or facial abnormality. anomaly, root,
n a general term for describing any deviation from normal found in a tooth root. anomaly marked deviation from normal. For specific anomalies see under anatomical location. developmental anomaly absence, deformity or excess of body parts as the result of faulty development of the embryo. lethal anomaly a defect which is incompatible with life and leads to the natural death or euthanasia on humane grounds of the neonate concerned. sex-limited anomaly limited in its occurrence by the sex of the neonate, e.g. cryptorchidism. sex-linked anomaly the gene responsible for the defect is located on the X or the Y chromosome, the sex determinative ones. developmental pertaining to development. developmental anomaly absence, deformity or excess of body parts as the result of faulty development of the embryo. Called also developmental defect. developmental defect see developmental anomaly (above). Patient discussion about developmental anomaly. Q. Is it a birth defect in children? I know about the causes of autism. Is it a birth defect in children? A. it's not an easy answer i'm afraid...there are congenital differences, but no "birth defect" that we can detect. there's a good pdf file that gives a full explanation about it...i think you'll find it useful: Read more or ask a question about developmental anomalyhttp://209.85.129.132/search?q=cache:U7PHTfTAZhYJ:www.nichd.nih.gov/publications/pubs/upload/autism_overview_2005.pdf+http://www.nichd.nih.gov/publications/pubs/upload/autism_overview_2005.pdf&hl=iw&ct=clnk&cd=1&gl=il Want to thank TFD for its existence?
