| autosomal dominant | <genetics> Requires only one affected parent have the trait to pass it to offspring. (02 Jan 1998) |

| kidney, polycystic, autosomal dominant | A genetic disorder with autosomal dominant inheritance characterised by multiple cysts in both kidneys and progressive deterioration of renal function. It is usually caused by a mutant gene at the pkd1 locus on the short arm of chromosome 16, though mutations elsewhere in the genome can also cause the disease. The age of onset of symptoms varies widely. (12 Dec 1998) |
|---|---|
| autosomal | Pertaining to an autosome. (05 Mar 2000) |
| autosomal gene | A gene located on any chromosome other than the sex chromosomes (X or Y). (05 Mar 2000) |
| autosomal recessive | <genetics> Mutation carried on an autosome that is deleterious only in homozygotes. (02 Jan 1998) |
| recessive, autosomal | A gene on a nonsex chromosome (an autosome) that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, cystic fibrosis (cf) is an autosomal recessive disorder. A cf child has the cf gene on both chromosome 7's (and so is said to be homozygous for cf). (12 Dec 1998) |
| kidney, polycystic, autosomal recessive | Rare genetic disorder with autosomal recessive inheritance characterised by multiple cysts in both kidneys and associated hepatic lesions. Serious manifestations are usually present at birth and there is high perinatal mortality. (12 Dec 1998) |
| genes, dominant | Genes that are reflected in the phenotype both in the homozygous and the heterozygous state. (12 Dec 1998) |
| permanent dominant idea | An exaggerated notion, belief, or delusion that persists, despite evidence to the contrary, and controls the mind, the obstinate conviction of a psychotic person regarding the correctness of his delusion. Synonym: idee fixe, overvalued idea, permanent dominant idea. (05 Mar 2000) |
| dominant | <genetics> A gene is said to be dominant if it expresses its phenotype even in the presence of a recessive gene. (09 Oct 1997) |
| dominant character | An inherited character determined by one kind of allele. See: phenotype. (05 Mar 2000) |
| dominant eye | The eye that is customarily used for monocular tasks. Synonym: master eye. (05 Mar 2000) |
| dominant frequency | The frequency occurring most often in an electroencephalogram. (05 Mar 2000) |
| dominant gene | dominance of traits |
| dominant hemisphere | That cerebral hemisphere containing the representation of speech and controlling the arm and leg used preferentially in skilled movements; usually the left hemisphere. (05 Mar 2000) |
| dominant idea | An idea that governs all one's actions and thoughts. (05 Mar 2000) |
