Penetrance The penetrance is unknown. based on the even segregation ratio in older generations of the known sca15 pedigrees, penetrance is likely to be high or complete in these families. the late age of onset in some cases (≤72 years) may confound attempts to establish penetrance. apparently unaffected parents of three affected siblings were reported in one japanese pedigree, although detailed information on the parents was not available [obayashi et al 2012]. based on pedigree analysis, a parent who would have been predicted to have a pathogenic variant in one of the german families died young (age 31) and was asymptomatic at the time of death, potentially concealing disease development [synofzik et al 2011]...

Summaries for Spinocerebellar Ataxia 15

About this section
NIH Rare Diseases : 50 spinocerebellar ataxia 15 (sca15) is a neurological condition characterized by slowly progressive gait and limb ataxia, often in combination with eye movement abnormalities and  balance, speech and swallowing difficulties. the onset of symptoms typically occurs between ages 7 and 66 years. the ability to walk independently is often maintained for many years following onset of symptoms. sca15 is caused by mutations in the itpr1 gene. it is inherited in an autosomal dominant manner. diagnosis is based on clinical history, physical examination, molecular genetic testing, and exclusion of other similar diseases. there is no effective treatment known to modify disease progression. patients may benefit from occupational and physical therapy for gait dysfunction and speech therapy for dysarthria.  last updated: 1/22/2013

MalaCards based summary : Spinocerebellar Ataxia 15, also known as spinocerebellar ataxia type 15, is related to spinocerebellar ataxia 29, congenital nonprogressive and spinocerebellar ataxia type 16, and has symptoms including scanning speech, gait ataxia and dysarthria. An important gene associated with Spinocerebellar Ataxia 15 is ITPR1 (Inositol 1,4,5-Trisphosphate Receptor Type 1), and among its related pathways/superpathways are Dopamine-DARPP32 Feedback onto cAMP Pathway and Neurophysiological process Glutamate regulation of Dopamine D1A receptor signaling. The drugs Pioglitazone and Metformin have been mentioned in the context of this disorder. Affiliated tissues include eye, testes and brain, and related phenotypes are behavior/neurological and growth/size/body region

UniProtKB/Swiss-Prot : 66 Spinocerebellar ataxia 15: Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA15 is an autosomal dominant cerebellar ataxia (ADCA). It is very slow progressing form with a wide range of onset, ranging from childhood to adult. Most patients remain ambulatory.

OMIM : 54 SCA15 is an autosomal dominant, adult-onset, very slowly progressive form of cerebellar ataxia. Most patients also have... (606658) more...
