The Genetics of TDP-43 Type C Neurodegeneration

Frontotemporal lobar degeneration TDP43 type C (TDP-C) is a rare and unique neurodegenerative disease that attacks the anterior temporal lobe. Recently, it was shown that Annexin-A11 and TDP-43 coaggregate specifically in TDP-C. Current literature on the genetic associations with TDP-C, reviewed here, lacks a discernible corpus of robust or replicated findings. In this study, using blood tissue, we completed whole genome sequencing to investigate ANXA11 and TARDBP genetic variants for their association with TDP-C. Then, we completed genome-wide hypothesis-free analyses using artificial intelligence to identify rare pathogenic variants associated with TDP-C.
