In this study, we generated 6 induced pluripotent stem cell (iPSC) lines derived from dermal fibroblasts of patients with sporadic amyotrophic lateral sclerosis (sALS). The fibroblasts were reprogrammed using non-integrating Sendai viruses containing four reprogramming factors OCT3/4, SOX2, KLF4 and C-MYC. The iPSC lines displayed normal molecular karyotype, expressed pluripotency markers and were capable of differentiating into three embryonic germ layers.

In this study, we describe the generation and characterization of induced pluripotent stem cell (iPSC) lines from familial long QT syndrome type 1 (LQT1) patients carrying the KCNQ1 c.1201dupC (p.Arg401fs) frame shift mutation by using non-integrational Sendai reprogramming method. The patient-specific iPSC lines harboring the c.1201dupC mutation on KCNQ1 gene expressed pluripotency markers and had the capacity to differentiate into three germ layers.

We generated a human induced pluripotent stem cell (iPSC) line from the skin fibroblasts of a 62-year-old female patient clinically diagnosed with sporadic Parkinson's disease (PD). The generated iPSCs maintained their normal karyotype, expressed pluripotency stem cell markers, and were demonstrated to be capable of differentiating into cells representative of the three embryonic germ layers. The generated line could be used for PD modeling in order to understand the mechanisms that influence the disorder.

We report the generation of three human induced pluripotent stem cell (hiPSC) lines (NUIGi047-A, NUIGi047-B, NUIGi047-C) from a healthy 7-year-old boy using non-integrational Sendai re-programming method expressing OCT4, SOX2, KLF4 and C-MYC. Stem cell characterization was confirmed through morphology, immunofluorescence staining and RT-qPCR. Differentiation potential in vitro was demonstrated to all three germ layers with STR lineage verification and normal molecular karyotyping through the process of re-programming.

Hundreds of rare risk factors have been identified for ASD, however, the underlying causes for ~70% of sporadic cases are unknown. Sporadic ASD models are thus essential for validating phenotypic commonality and drug suitability to the majority of patients. Here, we derived induced pluripotent stem cells (iPSCs) from one sporadic ASD child and one paternal control, using non-integrating Sendai viral methods. The iPSCs strongly expressed pluripotency markers and could be differentiated into three germ layers. Their normal karyotype was validated by genome SNP array. The availability of sporadic ASD-derived iPSCs offers an opportunity for phenotypic comparison with genetic ASD models.

NRXN1 deletions are commonly found in autism spectrum disorder (ASD) and other neurodevelopmental/neuropsychiatric disorders. Derivation of induced pluripotent stem cells (iPSCs) from different diseases involving different deletion regions are essential, as NRXN1 may produce thousands of splicing variants. We report here the derivation of iPSCs from a sibling control and an ASD proband carrying de novo heterozygous deletions in the middle region of NRXN1, using a non-integrating Sendai viral kit. The genotype and karyotype of the iPSCs were validated by whole genome SNP array. All iPSC lines highly expressed pluripotency markers and could be differentiated into three germ layers.

The majority of amyotrophic lateral sclerosis are sporadic (sALS) with no familial history or known genetic association, therefore a large cohort of disease models are required to identify common mechanisms or to test therapeutic interventions. Here we generated twelve induced pluripotent stem cell (iPSC) lines from human dermal fibroblasts of two healthy individuals and two sALS patients lacking common ALS mutations, using non-integrational Sendai virus expressing reprogramming factors OCT3/4, KLF4, SOX2 and c-MYC. The iPSC lines highly expressed pluripotency markers could be spontaneously differentiated into three embryonic germ layers, with no gross chromosomal aberrations or specific copy number variations.

NRXN1 copy number variation is a rare genetic factor commonly shared among autism spectrum disorder (ASD), schizophrenia, intellectual disability, epilepsy and developmental delay. Human induced pluripotent stem cells (iPSCs) are essential for disease modeling and drug discovery, but familial cases are particularly rare. We report here the derivation of familial iPSC lines from two controls and three ASD patients carrying NRXN1α+/-, using a non-integrating Sendai viral kit. The genotype and karyotype of the resulting iPSCs were validated by whole genome SNP array. All iPSC lines expressed comparable levels of pluripotency markers and could be differentiated into three germ layers.

KCNQ2 encodes the potassium-gated voltage channel Kv7.2, responsible for the M-current, which contributes to neuronal resting membrane potential. Pathogenic variants in KCNQ2 cause early onset epilepsies, developmental and epileptic encephalopathies. In this study, we generated three iPSC lines from dermal fibroblasts of a 5 year-old female patient with the KCNQ2 c.638C > T (p.Arg213Gln) pathogenic heterozygous variant and three iPSC lines from a healthy sibling control. These iPSC lines were validated by confirming the targeted mutation, SNP karyotyping, STR analysis, pluripotent gene expression, differentiation capacity into three germ layers, and were free of transgene integration and Mycoplasma.

Long QT syndrome (LQTS), an inherited cardiac ion channelopathy, is associated with ventricular arrhythmias and risk of sudden death. LQTS sub-type 2 (LQT2) is caused by pathogenic variants in KCNH2 encoding the α-subunit of Kv11.1, thus affecting the rapid component of delayed rectifier K+ current (IKr) channel during the action potential. In this study, non-integrational Sendai reprogramming method was used to generate an induced-pluripotent-stem-cell (iPSC) line carrying the KCNH2 c.2464G>A (p.Val822Met) pathogenic variant from a LQT2 patient. This patient-specific iPSC line NUIGi003-A harbouring the c.2464G>A variant expressed pluripotency markers and demonstrated the differentiation potential to all three germ layers.

De novo pathogenic variants in KCNA2 are implicated in causing a spectrum of human neurological disorders, in particular developmental and epileptic encephalopathies. KCNA2 encodes the voltage-gated delayed rectifier potassium channel Kv1.2, which is vital in regulating neuronal membrane potential and repolarization. In this study, we generated three iPSC lines with non-integrating Sendai viral vectors from dermal fibroblasts of an 11-year old female patient harboring the KCNA2 c.869T>G (p.Leu290Arg) pathogenic variant. The iPSC lines were validated with standardized procedures including the targeted mutation, free of transgene integration, SNP karyotyping, pluripotent gene expression, and differentiation capacity into three embryonic germ layers.

Long QT Syndrome type 1 (LQT1), an inherited cardiac ion channelopathy associated with arrhythmias and risk of sudden death, is caused by mutations in KCNQ1 encoding the α-subunit of Kv7.1, that affects the slow component of delayed rectifier K+ current (IKs) channel. In this study, the non-integrational Sendai reprogramming method was used to express four Yamanaka factors and to generate induced pluripotent stem cell (iPSC) lines carrying the KCNQ1 c.1697C>A (p.S566Y) mutation from familial LQT1 patients. The patient-specific iPSC lines harbouring the c.1697C>A mutation expressed pluripotency markers and had the capacity to differentiate into three germ layers.
