•
Intellectual Product
Source: Orphanet
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.

Definition

A rare disease with characteristics of slowly progressive and relatively pure ataxia described in 6 patients from one Australian family to date. The disease presents with oculomotor dysfunction, moderate dysarthria, and ataxia that progresses slowly and eventually leads to mobility impairment. Some patients have also reported mild hyperreflexia in the lower limbs. Rare manifestations include gaze-evoked nystagmus and dystonia. The causal gene has not yet been identified but it has been linked to chromosome 4q34.3-q35.1. [from SNOMEDCT_US]

Cerebellar ataxia
MedGen UID:
849
•Concept ID:
C0007758
•
Disease or Syndrome
Cerebellar ataxia refers to ataxia due to dysfunction of the cerebellum. This causes a variety of elementary neurological deficits including asynergy (lack of coordination between muscles, limbs and joints), dysmetria (lack of ability to judge distances that can lead to under- or overshoot in grasping movements), and dysdiadochokinesia (inability to perform rapid movements requiring antagonizing muscle groups to be switched on and off repeatedly).

Dysarthria
MedGen UID:
8510
•Concept ID:
C0013362
•
Mental or Behavioral Dysfunction
Dysarthric speech is a general description referring to a neurological speech disorder characterized by poor articulation. Depending on the involved neurological structures, dysarthria may be further classified as spastic, flaccid, ataxic, hyperkinetic and hypokinetic, or mixed.

Cerebellar atrophy
MedGen UID:
196624
•Concept ID:
C0740279
•
Disease or Syndrome
Cerebellar atrophy is defined as a cerebellum with initially normal structures, in a posterior fossa with normal size, which displays enlarged fissures (interfolial spaces) in comparison to the foliae secondary to loss of tissue. Cerebellar atrophy implies irreversible loss of tissue and result from an ongoing progressive disease until a final stage is reached or a single injury, e.g. an intoxication or infectious event.
