Generation of a human induced pluripotent stem cell line (UEFi003-A) carrying heterozygous A673T variant in amyloid precursor protein associated with a reduced risk of Alzheimer's disease.

A673T mutation in the amyloid precursor protein (APP) is a rare variant associated with a reduced risk of late-onset Alzheimer's disease (AD) and age-related cognitive decline. The A673T mutation decreases beta-amyloid (Aß) production and aggregation in neuronal cultures in vitro. Here we have identified a Finnish non-diseased male individual carrying a heterozygous A673T mutation, obtained a skin biopsy sample from him, and generated an iPSC line using commercially available integration-free Sendai virus-based kit. The established iPSC line retained the mutation, expressed pluripotency markers, had a normal karyotype, and differentiated into all three germ layers in vitro.

Generation of a human induced pluripotent stem cell line (LL008 1.4) from a familial Alzheimer's disease patient carrying a double KM670/671NL (Swedish) mutation in APP gene.

A double mutation (KM670/671NL) in amyloid precursor protein gene (APP) is causative for familial Alzheimer's disease and has been shown to increase the total Aß burden. Here we report the generation and characterization of an iPSC line from a fAD patient carrying APP KM670/671NL. The generated iPSCs retained the mutation, expressed pluripotency markers, showed a normal karyotype and differentiated into all three germ layers. This iPSC line can be used, for example, in disease modeling and mechanistic studies. Resource table.

Generation of a human induced pluripotent stem cell line from a patient with a rare A673T variant in amyloid precursor protein gene that reduces the risk for Alzheimer's disease.

An amyloid precursor protein (APP) A673T mutation was found to be protective against Alzheimer's disease (AD) and cognitive decline in the Icelandic population and to associate with decreased levels of plasma ß-amyloid in a Finnish population-based cohort. Human fibroblasts from a Finnish male individual carrying the protective mutation were used to generate integration-free induced pluripotent stem cell (iPSCs) line by Sendai virus technology. The iPSC line retained the mutation and expressed pluripotency markers, had a normal karyotype and differentiated into all three germ layers.
