Journey through ARSACS: Insights from a case series of seven patients - A single centre study and review of Indian cohort.
Background: In this study we describe the clinical, and investigations profile of 7 cases of autosomal-recessive spastic-ataxia of Charlevoix-Saguenay (ARSACS).
Methods: We performed retrospective chart review of genetically proven cases of ARSACS from our database. Additionally, we reviewed literature for reported cases of ARSACS from India.
Result: All seven patients had onset within the first-decade. As per the available data, all had walking difficulty (7/7), spastic-ataxia (7/7), classical neuroimaging findings (7/7), sensory-motor demyelinating polyneuropathy (6/6), abnormal evoked-potentials (5/5) and thickened retinal nerve fiber layer (3/3). Exome sequencing revealed 8 pathogenic/likely-pathogenic unique variants (6 novel) in SACS gene. Additional 21 cases (18 families) of ARSACS that could be identified from India had similar clinical and investigational findings. The most common c.8793delA variant may have a founder effect.
Conclusion: Our series adds to the previously reported cases of ARSACS from India and expands the genetic spectrum by adding 6 novel variants.
