SQSTM1 gene encodes a protein called p62 that acts as an autophagy receptor in the degradation of protein molecules. A homozygous deletion variant that changes the frame shift in the SQSTM1 gene named c.790 Del A .T was detected in case childhood onset and progressive neurodegeneration with ataxia, and gaze palsy.
Cerebrotendinous xanthomatosis is a rare autosomal recessive lipid storage syndrome defined clinically by the triad of progressive neurodegeneration, juvenile cataracts and tendon xanthomas in adults. It is treatable, and a prompt diagnosis can improve outcomes. We describe a patient with this condition who presented with progressive ataxia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
