| malignancy and immunodeficiency | <radiology> High risk of malignancy (especially lymphoma/leukaemia, GI tumours): X-linked agammaglobulinaemia (Bruton's), common variable immunodeficiency, severe combined immunodeficiency (SCID kids), ataxia-telangectasia, Wiscott-Aldrich syndrome, selective IgA deficiency (12 Dec 1998) |

| Papillon-Leage and Psaume syndrome | <syndrome> An inherited syndrome, lethal in males, with varying combinations of defects of the oral cavity, face, and hands, including lobulated or bifid tongue, cleft or pseudocleft palate, tongue tumours, missing or malpositioned teeth, hypoplastic nasal alar cartilage, depressed nasal bridge, brachydactyly, clinodactyly, incomplete syndactyly, and, frequently, mental retardation. There are two subtypes recognised. Type I (papillon-leage and psaume syndrome, gorlin-psaume syndrome) is inherited as an x-linked dominant trait and is found only in females and XXY males. Type II (mohr syndrome) is inherited as an autosomal recessive trait. Inheritance: autosomal recessive and X-linked. Synonym: OFD syndrome, orofaciodigital syndrome, Papillon-Leage and Psaume syndrome. (05 Mar 2000) |

| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
| maternal age 35 and over | Pregnancy in women 35 or more years of age. It is used for normal pregnancies and for problems of pregnancy occurring in a woman's late reproductive years. These include effects on the mother's physical and mental health as well as risks of perinatal mortality and foetal abnormality. (12 Dec 1998) |
| VH and VL genes/domains | VH and VL genes define in part the sequences of the variable heavy and light regions of immunoglobulin molecules. VH and VL domains are the regions of amino acid sequence so defined. J genes and, in the case of the heavy chain, a D gene (D=diversity) also define these regions. Gene rearrangement also plays a role in determining the sequences in which the genes are joined as the DNA of the immunoglobulin producing cell matures. (18 Nov 1997) |
