Abstract

LAP1 is an inner nuclear membrane protein encoded by TOR1AIP1. A homozygous c.961C > T loss of function mutation in TOR1AIP1 that affects both isoforms of LAP1 was recently described. This mutation leads to the development of a severe multisystemic nuclear envelopathy syndrome. Here we describe the generation and characterization of two human induced pluripotent stem cell (hiPSC) lines derived from skin fibroblasts of two patients carrying the homozygous c.961C > T mutation. These novel lines can be used as a powerful tool to investigate the molecular mechanism by which LAP1 deficiency leads to the development of this severe hereditary disorder.
