Very little is known about apoC-I in the context of bvFTD, other than that there are differences in linkage disequilibrium at the 19q13-q13.2 chromosomal region between bvFTD and primary progressive aphasia (Seripa et al., 2012), which is another subtype of FTD. The gene discussed is APOC1; the disease is behavioral variant of frontotemporal dementia.
