Abstract

Bi-allelic variants in the subunits of the adaptor protein complex 4 lead to childhood-onset, complex hereditary spastic paraplegia (AP-4-HSP): SPG47 (AP4B1), SPG50 (AP4M1), SPG51 (AP4E1), and SPG52 (AP4S1). Here, we describe the generation of induced pluripotent stem cells (iPSCs) from three AP-4-HSP patients with compound-heterozygous, loss-of-function variants in AP4B1 and sex-matched parents. Fibroblasts were reprogrammed using non-integrating Sendai virus. iPSCs were characterized according to standard protocols including karyotyping, embryoid body formation, pluripotency marker expression and STR profiling. These first iPSC lines for SPG47 provide a valuable resource for studying this rare disease and related forms of hereditary spastic paraplegia.
