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.

Ebstein's anomaly, showing displacement of the septal and posterior leaflets of the tricuspid valve into the right ventricle and accompanied by a patent foramen ovale.

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.

n.

A deviation from the average or norm.

anomaly (nom´lē),

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.
