The PPP2R2B gene, expressed highly in the brain, harbours trinucleotide CAG repeats in the 5'UTR region, in the range of 7-42 repeats. Individuals carrying CAG repeats greater than 43 have been associated to manifest a neurodegenerative disease condition termed as Spinocerebellar Ataxia type 12 (SCA12). An iPSC line from an adult male diagnosed with SCA12 presenting symptoms of gait (Gait Dominance) was generated. It showed pluripotency and trilineage markers without any chromosomal abnormality. This line can be utilized as an essential resource in enhancing our understanding of the molecular pathogenic mechanisms underlying SCA12 by facilitating generation of various neuronal cell types.

Friedreich's ataxia is a spinocerebellar degenerative disease caused by microsatellite (GAA.TTC)n repeat expansion in the first intron of FXN gene. Here, we developed iPSC lines from an FRDA patient (IGIBi016-A) and non-FRDA healthy control (IGIBi017-A). Both iPSC lines displayed typical iPSC morphology, expression of pluripotency markers, regular karyotypes (46, XY; 46, XX), capacity to grow into three germ layers, and FRDA hallmark -GAA repeat expansion and decreased FXN mRNA. Through these iPSC lines, FRDA phenotypes may be replicated in the in vitro assays, by creating neuron subtypes, cardiomyocytes and 3D organoids, for molecular and cellular biomarkers and therapeutic applications.

Friedreich's ataxia (FRDA) is a rare neurodegenerativedisorder caused by over expansion of GAA repeats in thefirstintron ofFXN gene. Here, we generated two iPSC lines from FRDA patients with biallelic expansion of GAA repeats in the first intron ofFXNgene.IGIBi014-A and IGIBi015-Aboth iPSC lines demonstrated characteristics of pluripotency, normal karyotypes (46, XY),the capacity to differentiate into all three germ layers, and the ability to sustain the GAA repeat expansion with decreased FXN mRNA expression. These cell lines will be utilized to comprehend the pathophysiology of the illness and the FRDA's predictive phenotypes.

Human Kinesin Family Member 5A (KIF5A) gene mutations have been identified as a putative genetic cause of amyotrophic lateral sclerosis (ALS). Disease modelling using human-induced pluripotent stem cells (HiPSCs) is the next-generation approach to studying numerous human diseases. For the current investigation, we report the generation of patient-specific KIF5A iPSC lines with a mutation at the splice site mutation (c.3020 + 3 A > T) in the intronic region. The resulting line displayed markers for pluripotency, a healthy karyotype, the ability to differentiate into three germ layers in vitro, vector clearance, the KIF5A mutation, STR-based genomic identity, and contamination-free culture.

Biallelic PRKG2 (Protein Kinase, cGMP dependent Type-2) mutations cause a novel acromesomelic dysplasia PRKG2 type. We report generation of induced pluripotent stem cell line from lymphoblastoid cell lines of the patient carrying the reported frameshift mutation (p.Asn164Lysfs*2). The derived iPSC line exhibits all the features of pluripotency, free of major genetic alterations due to reprogramming process and has the capability to differentiate into three germ layers. This iPSC cell line may provide an opportunity to investigate the effect of PRKG2 mutations upon FGF (fibroblast-growth-factor) induced MAPK signalling involved in chondrocyte proliferation in-vitro and may aid in possible therapeutic screening of novel biomolecules.

Duchenne muscular dystrophy (DMD) is an X-linked recessive disorder with defect in dystrophin gene that shows features of degeneration of muscle tissue at an early age. Here, we describe iPSC lines generated from LCL of two patients of Indian origin carrying 46-48 and 49-50 exons deletions in DMD. The resulting iPSC lines IGIBi006-A and IGIBi008-A showed all the characteristic features of pluripotency, differentiated into cells of three germ layers in vitro and have no major genetic alterations due to reprogramming process. These lines can serve as a useful cell model for studying disease pathogenesis and will aid in precision therapy.

Friedreich's ataxia is a neurodegenerative disorder caused by the hyper expansion of (GAA-TTC)n triplet repeats in the first intron of the FXN gene. Here, we generated iPSC lines from two individuals with FRDA, both of whom have homozygous GAA repeat expansion in the first intron of FXN gene. Both iPSC lines demonstrated characteristics of pluripotency, including expression of pluripotency markers, stable karyotypes and ability to develop into all three germ layers, and presence of GAA repeat expansion with reduced FXN mRNA expression. These iPSC lines will serve as invaluable tools for investigating the pathophysiology and phenotypes of FRDA.
