Polycystic Kidney, Autosomal Dominant
Mice, Inbred Strains
Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

Optic Atrophy, Autosomal Dominant
Dominant optic atrophy is a hereditary optic neuropathy causing decreased visual acuity, color vision deficits, a centrocecal scotoma, and optic nerve pallor (Hum. Genet. 1998; 102: 79-86). Mutations leading to this condition have been mapped to the OPA1 gene at chromosome 3q28-q29. OPA1 codes for a dynamin-related GTPase that localizes to mitochondria.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Polycystic Kidney Diseases
The presence of apparently similar characters for which the genetic evidence indicates that different genes or different genetic mechanisms are involved in different pedigrees. In clinical settings genetic heterogeneity refers to the presence of a variety of genetic defects which cause the same disease, often due to mutations at different loci on the same gene, a finding common to many human diseases including ALZHEIMER DISEASE; CYSTIC FIBROSIS; LIPOPROTEIN LIPASE DEFICIENCY, FAMILIAL; and POLYCYSTIC KIDNEY DISEASES. (Rieger, et al., Glossary of Genetics: Classical and Molecular, 5th ed; Segen, Dictionary of Modern Medicine, 1992)
A familial, cerebral arteriopathy mapped to chromosome 19q12, and characterized by the presence of granular deposits in small CEREBRAL ARTERIES producing ischemic STROKE; PSEUDOBULBAR PALSY; and multiple subcortical infarcts (CEREBRAL INFARCTION). CADASIL is an acronym for Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy. CADASIL differs from BINSWANGER DISEASE by the presence of MIGRAINE WITH AURA and usually by the lack of history of arterial HYPERTENSION. (From Bradley et al, Neurology in Clinical Practice, 2000, p1146)
Incoordination of voluntary movements that occur as a manifestation of CEREBELLAR DISEASES. Characteristic features include a tendency for limb movements to overshoot or undershoot a target (dysmetria), a tremor that occurs during attempted movements (intention TREMOR), impaired force and rhythm of diadochokinesis (rapidly alternating movements), and GAIT ATAXIA. (From Adams et al., Principles of Neurology, 6th ed, p90)
A type of mutation in which a number of NUCLEOTIDES deleted from or inserted into a protein coding sequence is not divisible by three, thereby causing an alteration in the READING FRAMES of the entire coding sequence downstream of the mutation. These mutations may be induced by certain types of MUTAGENS or may occur spontaneously.

Epidermolysis Bullosa Dystrophica
Form of epidermolysis bullosa characterized by atrophy of blistered areas, severe scarring, and nail changes.

- In a few breeds (Scottish terrier, German wirehair, and Chesapeake retriever) individuals with one normal and one abnormal gene are asymptomatic carriers and all affected individuals have two abnormal genes. (angelfire.com)
- If these individuals survive to breed, they transmit and abnormal gene to all of their offspring. (angelfire.com)
- Only one copy of the abnormal gene is required to produce the disease. (encyclopedia.com)
- Both males and females can express the disease and also transmit the abnormal gene. (encyclopedia.com)
- The parents of the affected person are called carriers, as they carry only one copy of the abnormal gene and do not express the disease. (encyclopedia.com)
- In an autosomal dominant disease, if you inherit the abnormal gene from only one parent, you can get the disease. (umm.edu)
- The abnormal gene dominates. (umm.edu)
- This disease can also occur as a new condition in a child when neither parent has the abnormal gene. (umm.edu)
- Children who do not inherit the abnormal gene will not develop or pass on the disease. (umm.edu)
- If someone is diagnosed with an autosomal dominant disease, their parents should also be tested for the abnormal gene. (umm.edu)
Allele is dominant2
- Mutations in the genes associated with combined pituitary hormone deficiency can result in abnormal differentiation of pituitary gland cells and may prevent the production of several hormones. (medlineplus.gov)
- Most people with combined pituitary hormone deficiency do not have identified mutations in any of the genes known to be associated with this condition. (medlineplus.gov)

- one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth. (wikipedia.org)
- Males and females with two abnormal genes are invariably affected with vWD and in many breeds bleeding is so severe that pups die in utero or soon after birth. (angelfire.com)
- Subsequently, it was reported that some cases of AOS appear to have autosomal recessive inheritance, perhaps with somewhat more severe phenotypic effects. (wikipedia.org)
- RP1 gene mutations have been discovered for the first time in autosomal recessive retinitis pigmentosa (RP), according to a study of consanguineous Pakistani families with the condition. (bmj.com)

- Mutations in the PRPH2 and RDH5 genes have been identified in patients with fundus albipunctatus. (cags.org.ae)
- 9 , 10 , 13 Some patients with autosomal dominant dRTA remain asymptomatic until adolescence or adulthood, whereas others and those with recessive disease may be severely affected in infancy, with impaired growth and early NC eventually leading to renal insufficiency. (aappublications.org)
- Many patients do not have mutations in genes identified so far, so further genes are expected to be involved in the pathogenesis of EDMD. (els.net)
