Analysis of SCA8, SCA10, SCA12, SCA17 and SCA19 in patients with unknown spinocerebellar ataxia: a Thai multicentre study
BACKGROUND About 50 % of Thai patients with adult-onset spinocerebellar ataxia (SCA) was Machado-Joseph disease (MJD), SCA1, SCA2 and SCA6. The author investigated further on less common SCAs in the patients without any known mutations. METHODS DNA samples of 82 index patients who were genetically excluded MJD, SCA1, SCA2, SCA6, SCA7 and dentatorubro-pallidoluysian atrophy (DRPLA) were examin...
متن کاملPossible reduced penetrance of expansion of 44 to 47 CAG/CAA repeats in the TATA-binding protein gene in spinocerebellar ataxia type 17.
BACKGROUND Spinocerebellar ataxia type 17 (SCA17) is an autosomal dominant cerebellar ataxia caused by expansion of CAG/CAA trinucleotide repeats in the TATA-binding protein (TBP) gene. Because the number of triplets in patients with SCA17 in previous studies ranged from 43 to 63, the normal number of trinucleotide units has been considered to be 42 or less. However, some healthy subjects in SC...
متن کاملDeactivation of TBP contributes to SCA17 pathogenesis.
Spinocerebellar ataxia type 17 (SCA17) is an autosomal dominant cerebellar ataxia caused by the expansion of polyglutamine (polyQ) within the TATA box-binding protein (TBP). Previous studies have shown that polyQ-expanded TBP forms neurotoxic aggregates and alters downstream genes. However, how expanded polyQ tracts affect the function of TBP and the link between dysfunctional TBP and SCA17 is ...

متن کاملCharacterization of Pathogenesis of SCA17 Transgenic Mice
TATA binding protein (TBP) is a general transcription factor that plays an important role in initiation of transcription. TBP gene is located in chromosome 6q27 and contains a CAG/CAA trinucleotide repeat region in its 5’ end, which encodes a polyglutamine (polyQ) tract. Spinocerebellar ataxias type 17 (SCA17) is an autosomal dominant cerebellar ataxia caused by TBP gene with an expanded polyQ ...
