Clinical Research Consortium for the Study of Cerebellar Ataxia (CRC-SCA)

CRC-SCA is a natural history study funded by the National Ataxia Foundation (NAF). The study enrolls individuals who have a confirmed diagnosis of SCA 1, 2, 3, 6, 7, 8, 10, 27B, or RFC1/CANVAS. Participants enrolled in CRC-SCA have extensive longitudinal clinical data available, with a cross-sectional biospecimen collection added in 2020. In 2023, CRC-SCA expanded to include follow-up biospecimen collections for a subset of participants.

CRCSCA

Study Participants

This study is still currently enrolling and projects to have a total enrollment of 200 subjects. Biospecimens are available from unaffected individuals with a family history of SCA1/SCA3 and participants with a recent diagnosis of SCA1 or SCA3.

Enrollment in CRC-SCA overlaps significantly with the Clinical Trial Readiness Study for SCA1 and SCA3 (READISCA), which is also banked with BioSEND.
