| Hereditary systemic amyloidosis v0.7 | APOA2 |
Eleanor Williams commented on gene: APOA2: Not associated with a relevant phenotype in OMIM but publications support association 4 cases reported: PMID: 29270531 - Prokaeva et al 2017 - report a family with renal amyloidosis associated with a novel stop codon mutation in APOA2 and the apoA-II variant, 78Leuext21 PMID: 12787390 - Yazaki et al 2003 - a Caucasian man with progressive renal dysfunction found to have amyloidosis. DNA sequencing of the apoAII gene in the proband showed a T to C transition at the first position of the stop codon indicating replacement of the stop codon by l-arginine (Arg) at residue 78. DNA from other family members was not available. PMID: 11401442 - Benson et al 2001 - report a family with hereditary renal amyloidosis. Sequence analysis of the apoAII gene of affected individuals showed heterozygosity for a single base substitution in the apoAII stop codon. The mutation results in extension of translation to the next in-frame stop codon 60 nucleotides downstream and is predicted to give a 21-residue C-terminal extension of the apoAII protein identical to that found in the amyloid. PMID: 11703582 - Yazaki et al 2001 - Caucasian male with proteinuria and renal biopsy revealed amyloid deposition in glomeruli. DNA analysis revealed heterozygosity for a G to C transversion at the second position of the stop-codon of apoA-II gene, suggesting a stop to serine substitution at codon 78. Western blot analysis and amino acid sequence analysis of the patient's plasma apoA-II showed both normal apoA-II and variant apoA-II with a 21-amino acid residue extension at the C-terminus. |
