✓ Peer-reviewed alzhub usefulness score 57 out of 100. Lewy body dementia

Topic: Brain proteins, microglia and lab models

We have previously reported a large Danish pedigree with autosomal dominant frontotemporal dementia (FTD) linked to chromosome 3 (FTD3). Here we identify a mutation in CHMP2B, encoding a component of the endosomal ESCRTIII complex, and show that it results in aberrant mRNA splicing in tissue samples from affected members of this family. We also describe an additional missense mutation in an unrelated individual with FTD. Aberration in the endosomal ESCRTIII complex may result in FTD and neurodegenerative disease.

Key findings

Why it matters

This 2005 study looked for the gene behind frontotemporal dementia (FTD) that was passed down through a large Danish family. It found a change in a gene called CHMP2B that disrupted how the gene's message was processed in tissue from affected family members, and a second CHMP2B change in one unrelated person with FTD. The authors propose that faults in the "ESCRTIII complex" "may" cause FTD; it is a finding from one family and one other person, and it is about frontotemporal dementia, not Alzheimer's or Lewy body dementia.
