Summaries for Spinocerebellar Ataxia 18

About this section

GARD: 19 Spinocerebellar ataxia type 18 (SCA18) is a very rare subtype of type I autosomal dominant cerebellar ataxia (ADCA type I; see this term). It is characterized by sensory neuropathy and cerebellar ataxia.

MalaCards based summary: Spinocerebellar Ataxia 18, also known as spinocerebellar ataxia type 18, is related to spastic paraparesis and aceruloplasminemia, and has symptoms including tremor and dysdiadochokinesis. An important gene associated with Spinocerebellar Ataxia 18 is IFRD1 (Interferon Related Developmental Regulator 1). Affiliated tissues include skeletal muscle, and related phenotypes are muscle weakness and areflexia

Orphanet: 58 Spinocerebellar ataxia type 18 (SCA18) is a very rare subtype of type I autosomal dominant cerebellar ataxia (ADCA type I; see this term). It is characterized by sensory neuropathy and cerebellar ataxia.

Disease Ontology: 11 An autosomal dominant cerebellar ataxia that is characterized by cerebellar ataxia and sensory neuropathy, has material basis in mutation on chromosome 7q22-q23.
