Generation of human induced pluripotent stem cells (hIPSCs) from sialidosis types I and II patients with pathogenic neuraminidase 1 mutations.

Sialidosis is an autosomal recessive lysosomal storage disease, belonging to the glycoproteinoses. The disease is caused by deficiency of the sialic acid-cleaving enzyme, sialidase 1 or neuraminidase 1 (NEU1). Patients with sialidosis are classified based on the age of onset and severity of the clinical symptoms into type I (normomorphic) and type II (dysmorphic). Patient-derived skin fibroblasts from both disease types were reprogrammed using the CytoTune™-iPS 2.0 Sendai Reprogramming Kit. iPSCs were characterized for pluripotency, three germ-layer differentiation, normal karyotype and absence of viral components. These cell lines represent a valuable resource to model sialidosis and to screen for therapeutics.
