AAV-mediated CBLN1 replacement rescues hereditary ataxia caused by biallelic CBLN1 variants

Mol Ther. 2026 Sep 2:S1525-0016(26)00772-0. doi: 10.1016/j.ymthe.2026.09.003. Online ahead of print. ABSTRACT Cbln1 is a secreted synaptic organizer required for parallel fiber-Purkinje cell (PF-PC) synapse integrity, climbing fiber (CF) refinement, and cerebellar motor learning, but has not previously been implicated in human disease. We identified biallelic CBLN1 missense variants (A63P and Y112C) in two unrelated […]
