Evaluating Glial Fibrillary Acidic Protein and Neurofilament Light as Potential Biomarkers for Spinocerebellar Ataxia 7.

ABSTRACT: Spinocerebellar ataxia type 7 (SCA7), a rare form of ataxia, possesses a wide phenotypic spectrum ranging from classic ataxic symptoms to blindness, multiorgan failure, cardiomyopathy, and early death among younger age groups. Biomarkers associated with disease progression and severity could aid in disease prognostication. We evaluated the utility of glial fibrillary acidic protein (GFAP) and neurofilament light (NfL) in distinguishing patients with SCA7 from healthy controls and estimating patient prognosis. GFAP and NfL levels were measured in 23 plasma and 20 cerebrospinal fluid (CSF) samples from asymptomatic (N = 3) and symptomatic SCA7 participants (N = 10) and from healthy controls (N = 8). GFAP concentrations were elevated in the plasma (82.7 pg/mL) and CSF (9318 pg/mL) of patients
