Abstract

|
We present a 33-year-old male patient with cerebellar ataxia. He was first considered to have a psychiatric conversion disorder but finally found to have chromosomal deletion in 7q31.2-31.32 involving Ca2+-dependent activator protein for secretion (CADPS) gene. When a targeted gene sequencing using next-generation sequencing panel and chromosomal microarray analysis were performed, an 8.6 Mb deletion within chromosome 7q31.2-31.32 was discovered. Deletion of CADPS gene in the 7q31.2-31.32 was suggested as the causative factor of cerebellar ataxia. Functional levels evaluated by Berg balance scale and modified Barthel index were improved via comprehensive rehabilitation including balance training and a dopamine agonist medication. To the best of our knowledge, this is the first report of chromosomal deletion in 7q31.2-31.32 including CADPS gene detected in patients with cerebellar ataxia.
