Added comment: At least 4 unrelated families with dementia as a prominent feature of the phenotype and stop loss or protein elongating variants, and a supporting mouse model. Variants that result in the generation of peptide, which is deposited as amyloid fibrils causing neuronal disfunction and dementia.
PMID: 10391242 - familial British dementia (FBD) stop loss variant (c.799T>A p.Ter267Arg) in British kindred with progressive dementia, spasticity, and cerebellar ataxia, with onset at around the fifth decade of life.
PMID: 10781099 - familial Danish dementia protein elongating variant (c.787_796dup p.Ser266fs) identified in a large Danish kindred with a dominant disorder characterised by cataracts, deafness, progressive ataxia, and dementia.
PMID: 33814452 - a Chinese patient with dementia, ataxia, deafness, and paraplegia and a heterozygous stop loss variant (p.*267Leuext*11)
ClinVar: SCV002059726.1 - likely pathogenic stop loss variant (c.800G>T p.Ter267Leu) similar to the FBD variant reported in an individual affected with ABri amyloidosis by Centogene AG
PMID: 20385796 - mouse model of Danish variant demonstrates amyloid deposition in brain (to a lesser extent in the cerebellum), and increased anxiety.

Added comment: A single missense variant L68Q causes Icelandic-type CAA, where brain haemorrhage is main presenting feature of the condition. Progressive multi-infarct dementia has been reported in at least 17 cases. Dementia has been reported as the presenting feature in 2 cases from the same family. The gene has also been reported as an Alzheimer's disease susceptibility loci, but there is modest risk associated with the homozygote (rs1064039) minor allele genotype, combined OR 1.6.

Added comment: Well-established cause of cerebral amyloid angiopathy. Loss of function is not the mechanism of disease. Disease-causing missense substitutions cause an increased accumulation of amyloid-beta protein in the walls of the arteries and capillaries of the meninges, cerebellar cortex and cerebral cortex, leading to the weakening and eventual rupture of these vessels.
