==Pathophysiology==
==Pathophysiology==
Fibrinogen A a-chain amyloidosis is a systemic amyloid disease with multivisceral and neurologic involvement, and is associated with cardiac amyloid deposition and amyloid angiopathy and atheromatosis.
Fibrinogen is a plasma protein with a crucial role in the coagulation cascade through its conversion to fibrin
It is composed of 2 identical sets of 3 polypeptide chains termed A α, B β, and γ, joined by disulfide bridging.
Each polypeptide is encoded by a distinct gene, FGA, FGB, and FGG.
The gene for the fibrinogen A α-chain with 610 amino acid residues is localized on chromosome 4 and has 6 exons.<ref name="pmid11460526">{{cite journal| author=Matsuda M, Sugo T| title=Hereditary disorders of fibrinogen. | journal=Ann N Y Acad Sci | year= 2001 | volume= 936 | issue=  | pages= 65-88 | pmid=11460526 | doi=10.1111/j.1749-6632.2001.tb03494.x | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=11460526  }} </ref> 
Mutations in any of the 3 genes encoding for fibrinogen polypeptides can cause dysfibrinogenemias, coagulation disorders caused by a variety of structural abnormalities in the fibrinogen molecule that result in abnormal fibrinogen function.

Overview

Fibrinogen A a-chain amyloidosis (AFib) is a systemic disease caused by extracellular deposition of insoluble amyloid fibrils composed of abnormal fibrinogen, arising from autosomal dominant mutations in the gene encoding AFib.

Historical Perspective

Fibrinogen A a-chain amyloidosis (AFib) was first discovered by Merill Benson et al., in 1993.[1]

Classification

Pathophysiology

Causes

Fibrinogen Aα-chain amyloidosis is caused by the extracellular deposition of amyloid fibrils induced by mutations in fibrinogen Aα-chain gene (FGA).[2]
