HA includes Hereditary amyloidogenic transthyretin (hATTRv) [123], amyloidosis derived from a fibrinogen variant (AFib), that is the most frequent HA in Northern Europe [124], variants of apolipoproteins (AI, AII, C-II, CIII), gelsolin (AGel), and lysozyme (ALys) [125]. Here, TTR is linked to amyloidosis.
