Summaries for Spinocerebellar Ataxia Type 19/22

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 98772Disease definitionSpinocerebellar ataxia type 19 (SCA19) is a very rare subtype of type I autosomal dominant cerebellar ataxia (ADCA type I; see this term). It is characterized by mild cerebellar ataxia, cognitive impairment, low scores on the Wisconsin Card Sorting Test measuring executive function, myoclonus, and postural tremor.EpidemiologyPrevalence is unknown. Only 12 cases in a 5-generation Dutch family have been reported to date.Clinical descriptionSCA19 presents in the 3rd decade of life with symptomatic disease onset ranging from 10 to 46 years. Onset symptoms of SCA22 (see this term) overlap significantly with those of SCA19 but with a more narrow age range of 35 to 46 years.EtiologyLinkage to locus 1p21-q21 has been proposed but the genemutation has not been identified.PrognosisPrognosis is good. SCA19 does not impact life expectancy to any major extent, and some patients live to over 80 years of age.Visit the Orphanet disease page for more resources.

MalaCards based summary : Spinocerebellar Ataxia Type 19/22, also known as spinocerebellar ataxia 19 and 22, is related to autosomal dominant cerebellar ataxia and epilepsy. An important gene associated with Spinocerebellar Ataxia Type 19/22 is KCND3 (Potassium Voltage-Gated Channel Subfamily D Member 3), and among its related pathways/superpathways are Transmission across Chemical Synapses and Dopamine-DARPP32 Feedback onto cAMP Pathway. Affiliated tissues include testes, skin and liver, and related phenotypes are nystagmus and diplopia
