- Myoclonic tremor (HP:0033054): A tremor-like cortical myoclonus. The tremulous movements are in fact small, high-frequency myoclonic jerks, induced by posture or action. They can be mild, but can also be more incapacitating. When present in the lower limbs, these may lead to gait disorders and even drop attacks. These tremor-like movements during action can be mistaken for essential tremor or epileptic seizures. Evidence: PCS. (PMID:29507423)
- Adult onset (HP:0003581): Onset of disease manifestations in adulthood, defined here as at the age of 16 years or later. Evidence: PCS. (PMID:29507423)
- Autosomal dominant inheritance (HP:0000006): 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. Evidence: PCS. (PMID:29507423)
These phenotypes are associated with the disease epilepsy, familial adult myoclonic, 6 (OMIM:618074).
