Generation of two iPSC lines (UMi038-A & UMi039-A) from siblings bearing an Alzheimer's disease-associated variant in SORL1

Abstract

Alzheimer's disease (AD) is the leading cause of dementia among older adults. SORL1, a top AD risk gene, encodes an endocytic receptor involved amyloid precursor protein (APP) trafficking and processing. Rare loss-of-function SORL1 variants are a strong genetic determinant of AD, and protein-truncating mutations have been found to be causal. We derived iPSCs from two siblings affected with early-onset AD who carry a rare protein-truncating deletion in SORL1 (c.4293delC) (Kunkle et al., 2017). The iPSC lines were characterized for pluripotency, differentiation potential, and genomic stability. These lines are a valuable resource for studying pathogenic mechanisms underlying AD.
