Functional variants of CFAP410 affect the DNA damage response leading to motor neuron degeneration - Implications for ALS.

ABSTRACT: Mutations in CFAP410, a basal body protein known to be required for the formation of primary cilia, have been identified as risk modifiers in amyotrophic lateral sclerosis (ALS), a devastating late onset neurodegenerative disorder with poor prognosis. CFAP410 is also implicated in the DNA damage response and interacts with Nek1, which has been shown to be mutated in ALS. Herein, we investigated the effect of knocking in an HA epitope tag and functional mutations into the endogenous Cfap410 gene by gene editing in mouse embryonic stem cells (mESCs). We show that primary cilia in these edited mESCs, as well as in the neural progenitors and neurons differentiated from them do not exhibit any significant difference in frequency. However, ESCs, neural progenitors, and neurons with knock-in Cfap
