Table 1: Summary of proteins responsible for amyloidosis, the corresponding abbreviations and the key characteristics associated with each.

Amyloidogenic protein	Abbreviation	Characteristics
Immunoglobulin light chain	AL	Primary amyloidosis, plasma cell dyscrasias. Cardiomyopathy, hepatomegaly, nephrotic syndrome.
Immunoglobulin heavy chain	AH	Plasma cell dyscrasias, renal involvement.
Transthyretin	ATTR	Familial amyloidosis, systemic, associated with peripheral neuropathy and cardiomyopathy.
Leukocyte chemotactic factor 2	ALECT 2	Renal dysfunction, lack of cardiac or nerve involvement.
Serum amyloid A	AA	Acquired, reactive, systemic, linked to inflammatory disorders or chronic infection. Proteinuria, loss of renal function.
Apolipoprotein A-I	AApoAI	Autosomal dominant systemic, organ involvement related to specific mutations.
Apolipoprotein A-II	AApoAII	Autosomal dominant systemic, renal failure.
Lysozyme	ALys	Autosomal dominant, GI and renal dysfunction.
Fibrinogen	AFib	Autosomal dominant, deposition in kidney, heart, liver, and spleen; prominent renal involvement.
Gelsolin	AGel	Autosomal dominant, polyneuropathy, corneal lattice dystrophy.
β2-microglobulin	Aβ2M	Hemodialysis-related amyloidosis with musculoskeletal manifestations.
