Leucine rich repeat kinase 2 (LRRK2) is the causative gene for autosomal-dominant familial forms of Parkinson's disease (PD). Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a female patient with LRRK2 c.4111A > G (p.I1371V) mutation by using the Sendai-virus delivery system. The resulting iPSCs had a normal karyotype. The iPSCs also showed pluripotency confirmed by immunofluorescent staining and differentiated into the three germ layers in vivo. This cellular model will provide a platform for studying the role of LRRK2 in the disease process.

A recessive mutation in PLA2G6, which is known to cause a heterogeneous neurodegenerative clinical spectrum, has recently been shown to be responsible for autosomal-recessive familial forms of Parkinson's disease (PD). Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a female patient with a homozygous PLA2G6 c.991G > T (p.D331Y) mutation by using the Sendai-virus delivery system. The resulting iPSCs showed pluripotency confirmed by immunofluorescent staining for pluripotency markers and differentiated into the 3 germ layers in vivo. This cellular model will provide a good resource for further pathophysiological studies of PD.

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by interactions between genetic and environmental factors. Leucine rich repeat kinase (LRRK2) is the most prevalent mutation in autosomal-dominant inheritance of PD. Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a female patient with p.I2012T mutation in LRRK2 gene by using the Sendai-virus delivery system. The resulting iPSCs had a normal karyotype. The iPSCs also showed pluripotency confirmed by immunofluorescent staining and differentiated into the 3 germ layers in vivo. This cellular model will provide a useful platform for further pathophysiological studies of PD.

Leucine rich repeat kinase (LRRK2) is the most prevalent genetic cause for Parkinson's disease. LRRK2 p.G2385R is an Asian specific genetic risk factor for sporadic Parkinson's disease. We generated two induced pluripotent stem cells (iPSCs), IBMS-iPSC-018-09 and IBMS-iPSC-020-01, from the peripheral blood mononuclear cells of two patients carrying LRRK2 p.G2385R variant by using the Sendai-virus delivery system. These iPSCs had a normal karyotype and exhibited pluripotency, such as an embryonic stem cell-like morphology, expression of pluripotent markers, and capacity to differentiate into three germ layers. This cellular model will provide a platform for pathophysiological studies of neurodegeneration in Parkinson's disease.

Aceruloplasminemia is a rare autosomal recessive disorder caused by mutations in the CP gene, encoding the copper-binding protein ceruloplasmin. A mutation in the CP gene results in brain and systemic iron overload, which is classified as a rare subtype of neurodegeneration with brain iron accumulation (NBIA). Here, we used the Sendai virus delivery system to generate induced pluripotent stem cells from peripheral blood mononuclear cells of a patient carrying the CP c.607+1 delG homozygous splicing mutation. The generated cell line retained the original genotype, expressed pluripotency markers, and differentiated into cells of the three germ layers.

aaWilson's disease (WD) is a rare genetic disorder of copper metabolism, and longitudinal follow-up studies are limited. We performed a retrospective analysis to determine the clinical characteristics and long-term outcomes in a large WD cohort.
