[[http://www.uniprot.org/uniprot/APOA1_HUMAN APOA1_HUMAN]] Defects in APOA1 are a cause of high density lipoprotein deficiency type 2 (HDLD2) [MIM:[http://omim.org/entry/604091 604091]]; also known as familial hypoalphalipoproteinemia (FHA). Inheritance is autosomal dominant.<ref>PMID:8240372</ref> <ref>PMID:8282791</ref>  Defects in APOA1 are a cause of the low HDL levels observed in high density lipoprotein deficiency type 1 (HDLD1) [MIM:[http://omim.org/entry/205400 205400]]; also known as analphalipoproteinemia or Tangier disease (TGD). HDLD1 is a recessive disorder characterized by the absence of plasma HDL, accumulation of cholesteryl esters, premature coronary artery disease, hepatosplenomegaly, recurrent peripheral neuropathy and progressive muscle wasting and weakness. In HDLD1 patients, ApoA-I fails to associate with HDL probably because of the faulty conversion of pro-ApoA-I molecules into mature chains, either due to a defect in the converting enzyme activity or a specific structural defect in Tangier ApoA-I.<ref>PMID:8240372</ref> <ref>PMID:8282791</ref>  Note=A mutation in APOA1 is the cause of amyloid polyneuropathy-nephropathy Iowa type (AMYLIOWA); also known as amyloidosis van Allen type or familial amyloid polyneuropathy type III. AMYLIOWA is a hereditary generalized amyloidosis due to deposition of amyloid mainly constituted by apolipoprotein A1. The clinical picture is dominated by neuropathy in the early stages of the disease and nephropathy late in the course. Death is due in most cases to renal amyloidosis. Severe peptic ulcer disease can occurr in some and hearing loss is frequent. Cataracts is present in several, but vitreous opacities are not observed.<ref>PMID:8240372</ref> <ref>PMID:8282791</ref> <ref>PMID:3142462</ref> <ref>PMID:2123470</ref>  Defects in APOA1 are a cause of amyloidosis type 8 (AMYL8) [MIM:[http://omim.org/entry/105200 105200]]; also known as systemic non-neuropathic amyloidosis or Ostertag-type amyloidosis. AMYL8 is a hereditary generalized amyloidosis due to deposition of apolipoprotein A1, fibrinogen and lysozyme amyloids. Viscera are particularly affected. There is no involvement of the nervous system. Clinical features include renal amyloidosis resulting in nephrotic syndrome, arterial hypertension, hepatosplenomegaly, cholestasis, petechial skin rash.<ref>PMID:8240372</ref> <ref>PMID:8282791</ref> <ref>PMID:1502149</ref>
