Associated with Apolipoprotein C-III deficiency (#614028) only in OMIM.

PMID: 26790392 - Valleix et al 2016 - report a French family with severe renal amyloidosis and hypotriglyceridemia, both caused by a novel D25V apoC-III variant. The D25V apoC-III variant was only found in family members affected with amyloidosis, hypotriglyceridemia and reduced apoC-III levels, and not in healthy normotriglycemic family members.

A PubMed search with APOC3 or Apolipoprotein C-III and amyloidosis did not find any further cases.
