RESUMO
The human iPSC cell lines, PLANFiPS1-Sv4F-1 (RCPFi004-A), PLANFiPS2-Sv4F-1 (RCPFi005-A), PLANFiPS3-Sv4F-1 RCPFi006-A), derived from dermal fibroblast from three patients suffering PLAN (PLA2G6-associated neurodegeneration; MIM 256600) caused by mutations in the PLA2G6 gene, was generated by non-integrative reprogramming technology using OCT3/4, SOX2, CMYC and KLF4 reprogramming factors. The pluripotency was assessed by immunocytochemistry and RT-PCR. Differentiation capacity was verified in vitro. This iPSC line can be further differentiated toward affected cells to better understand molecular mechanisms of disease and pathophysiology.

The human induced pluripotent stem cell (hiPSC) line RP1-FiPS4F1 generated from the patient with autosomal recessive retinitis pigmentosa (arRP) caused by homozygous Ser331Cysfs*5 mutation in Mer tyrosine kinase receptor (MERTK) was genetically corrected using CRISPR/Cas9 system. Two isogenic hiPSCs lines, with heterozygous and homozygous correction of c.992_993delCA mutation in the MERTK gene were generated. These cell lines demonstrate normal karyotype, maintain a pluripotent state, and can differentiate toward three germ layers in vitro. These genetically corrected hiPSCs represent accurate controls to study the contribution of the specific genetic change to the disease, and potentially therapeutic material for cell-replacement therapy.

The human iPSC cell line, CARS-FiPS4F1 (ESi064-A), derived from dermal fibroblast from the apparently healthy carrier of the mutation of the gene SACSIN, was generated by non-integrative reprogramming technology using OCT3/4, SOX2, CMYC and KLF4 reprogramming factors. The pluripotency was assessed by immunocytochemistry and RT-PCR. This iPSC line can be used as control for Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) disease.

Bernard Soulier Syndrome (BSS) is an inherited rare platelet disorder characterized by mutations in the platelet glycoprotein complex GPIb-IX-V. We generated an induced pluripotent stem cell (iPSC) line from a BSS patient with a mutation p.Asn45Ser in the GPIX locus (BSS2-PBMC-iPS4F24). Peripheral blood mononuclear cells were reprogrammed using non-integrative viral transduction. Characterization of BSS2-PBMC-iPS4F24 included mutational analysis of GPIX locus, analysis of conventional pluripotency-associated factors at mRNA and protein level and in vitro and in vivo differentiation studies. This iPSC line will provide a powerful tool to study the biology of BSS disease.
