Generation of two induced pluripotent stem cell lines (HIMRi006-A and HIMRi007-A) from Pompe patients with infantile and late disease onset.

Here we present the generation of HIMRi006-A and HIMRi007-A Pompe disease (PD) patient derived human induced pluripotent stem cell (hiPSC) lines. HIMRi006-A represents an infantile onset disease (IOPD) phenotype caused by a homozygous c.307 T > G mutation in the GAA gene. HIMRi007-A is characterized by heterozygous mutations c.-32-13 T > G/c.1716C > G and is associated with an adult onset of disease symptoms (LOPD). Both lines are generated via lentiviral expression of OCT4, SOX2, KLF4, and c-MYC. The lines display a typical embryonic stem cell morphology, express pluripotency markers, retain a normal karyotype (46, XX/XY) and have the differentiation capacity in all three germ layers. Altogether, both lines provide a resource tool to the community for future in depth molecular studies of PD pathomechanism.

Generation of two hiPSCs lines of two patients carrying truncating mutations in the dimerization domain of filamin C.

Here we introduce the human induced pluripotent stem cell lines (hiPSCs), HIMRi004-A and HIMRi005-A from dermal fibroblasts of a 48-year-old female (HIMRi004-A) carrying missense mutation that translate to the first described filamin C isoform p.W2710X and from a 56-year-old female (HIMRi005-A) carrying a recently described mutation in the same domain p.Y2704X. Both lines are generated via lentiviral expression of OCT4, SOX2, KLF4 and c-MYC. The lines display a typical embryonic stem cell-like morphology, express pluripotency markers, retain a normal karyotype (46, XX) and have the differentiation capacity in all three germ layers. The two lines can be used to elucidate the pathomechanisms of FLNC myofibrillar myopathies and to develop novel therapeutic options.

Generation of two human iPSC lines (HIMRi002-A and HIMRi003-A) derived from Caveolinopathy patients with rippling muscle disease.

Here we introduce the human induced pluripotent stem cell lines (hiPSCs), HIMRi002-A and HIMRi003-A, generated from cultured dermal fibroblasts of 61-year-old (HIMRi002-A) and 38-year-old (HIMRi003-A) female patients, carrying a known heterozygous pathogenic variant (p.A46T) in the Caveolin 3 (CAV3) gene, via lentiviral expression of OCT4, SOX2, KLF4 and c-MYC. HIMRi002-A and HIMRi003-A display typical embryonic stem cell-like morphology, carry the p.A46T CAV3 gene mutation, express several pluripotent stem cell markers, retain normal karyotype (46, XX) and can differentiate in all three germ layers. We postulate that the HIMRi002-A and HIMRi003-A iPSC lines can be used for the characterization of CAV3-associated pathomechanisms and for developing new therapeutic options.

Generation of a human iPSC line (HIMRi001-A) from a patient with filaminopathy.

Here we introduce the human induced pluripotent stem cell (hiPSC) line HIMRi001-A generated from cultured dermal fibroblasts of a 60-year-old male patient with a myofibrillar myopathy, carrying a heterozygous c.4984C > T [p.Q1662X] mutation in the filamin C (FLNC)-gene, via lentiviral expression of OCT4, SOX2, KLF4 and c-MYC. HIMRi001-A displays typical embryonic stem cell-like morphology, carries the c.4984C > T FLNC gene mutation, expressed several pluripotent stem cell makers, retained normal karyotype (46, XY) and holds the potential to differentiate in all three germ layers. We postulate that HIMRi001-A can be used for the elucidation of FLNC-associated pathomechanisms and for developing new therapeutic options.
