Phenotype (from MGI, Zfin or HPO)
IDPhenotypeDefinition Genetic BG
 HP:0000006 Autosomal dominant inheritance "A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele." [HPO:curators]

 HP:0001249 Mental retardation 
Show

 HP:0001250 Seizures "Seizures are an intermittent `abnormality of the central nervous system` (FMA:HP:0002011) due to a sudden, excessive, disorderly discharge of cerebral neurons and characterized clinically by some combination of disturbance of sensation, loss of consciousness, impairment of psychic function, or convulsive movements." [HPO:probinson]
Show

 HP:0001251 Ataxia "Ataxia is a nonspecific neurological sign and symptom consisting of gross lack of coordination of muscle movements. Ataxia is caused by dysfunction of one or more parts of the nervous system including the cerebellum, the sensory nervous system, the vestibular system, or the cerebral cortex." [HPO:curators]
Show

 HP:0001336 Myoclonus "Very brief, involuntary random muscular contractions occurring at rest, in response to sensory stimuli, or accompanying voluntary movements." [HPO:curators]
Show

 HP:0001337 Tremor "An unintentional, oscillating to-and-fro muscle movement." [HPO:curators]
