TMEM106B Modifies TDP-43 Pathology in Human ALS Brain and Cell-Based Models of TDP-43 Proteinopathy

0
Researchers investigated the influence of genotypes at TMEM106B, a locus associated with risk for frontotemporal lobar degeneration with TAR DNA-binding protein-43 inclusions (FTLD-TDP), and hexanucleotide repeat expansions in C9orf72, a known genetic cause for both amyotrophic lateral sclerosis and FTLD-TDP, on global TDP-43 pathology and regional distribution of TDP-43 pathology in 899 postmortem cases from a spectrum of neurodegenerative diseases.
