reach
"Mechanistically, it is not yet fully understood how the ATXN3 variants contribute to ataxia."

reach
"Transcriptional dysregulation has been described in spinocerebellar ataxia type 3/Machado-Joseph disease (SCA3/MJD), an autosomal dominant ataxia caused by a polyglutamine expansion in the ataxin-3 protein."

reach
"The most common, dominantly inherited ataxia worldwide, Spinocerebellar Ataxia Type 3 (SCA3), also known as Machado-Joseph Disease, is caused by a mutation in the deubiquitinase (DUB) ataxin-3 (Atxn3)[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"As a part of the routine genetic testing, they were tested using standard laboratories protocols for the ataxia-causing known genes in India—SCA1, SCA2, SCA3, SCA7, and SCA12."

reach
"Clinically, MJD leads to progressive ataxia and pyramidal signs, accompanied by a wide array of symptoms such as amyotrophy, gait imbalance, ophthalmoplegia, speech difficulties and dysphagia [77]."

reach
"Mutation of USP14 in mice or ataxin-3 in humans causes ataxia (Crimmins et al., 2006; Duenas et al., 2006) , whereas the S18Y allele of human UCH-L1 confers protection against sporadic Parkinson's disease."

reach
"Spinocerebellar ataxia type 3 (SCA3), a neurodegenerative condition caused by a CAG repeat expansion in the ATXN3 gene, leads to progressive ataxia affecting balance, gait, and speech."
