Functional effects of tau gene mutations ΔN296 and N296H

Abstract excerpt

Mutations in the tau gene cause frontotemporal dementia and parkinsonism linked to chromosome-17 (FTDP-17). Functionally, about half of the known mutations increase the alternative mRNA splicing of exon 10 of the tau gene, resulting in the overproduction of tau isoforms with four microtubule-binding repeats. The other mutations reduce the ability of tau to interact with microtubules, with some mutations also...
