Two iPSC clones, NCCSi008-A and NCCSi008-B, were generated from a healthy male individual of Indian origin by reprogramming his CD4 T cells with an integration free Sendai viral vector. The established iPSC clones showed high alkaline phosphatase (ALP) activity, expression of pluripotency markers, a normal male karyotype consistent with the donor gender (46, XY) and has potential for multi-lineage differentiation. These iPSC lines of Indian origin would serve as valuable resources for disease modeling, drug development and screening.

A rare neurodevelopmental disorder has been linked to a well-conserved splice site variant in the TRAPPC4 gene (c.454 + 3A > G), which causes mis-splicing of TRAPPC4 transcripts and reduced levels of TRAPPC4 protein. Patients present with severe progressive neurological symptoms including seizures, microcephaly, intellectual disability and facial dysmorphism.

Retrotransposable elements are implicated in genome rearrangements and gene expression alterations that result in various human disorders. In the current study, we sought to investigate the potential effects of long interspersed elements-1 (LINE-1) overexpression on the integrity and methylation of DNA and on the expression of three major pluripotency factors (OCT4, SOX2, NANOG) during the preimplantation stages of human embryo development. Human MI oocytes were matured in vitro to MII and transfected through intracytoplasmic sperm injection (ICSI) either with an EGFP vector carrying a cloned active human LINE-1 retroelement or with the same EGFP vector without insert as control.

The mitochondrial genome (mtDNA) is an important source of inherited extranuclear variation. Clonal increases in mtDNA mutation heteroplasmy have been implicated in aging and disease, although the impact of this shift on cell function is challenging to assess. Reprogramming to pluripotency affects mtDNA mutation heteroplasmy.

Myotonic dystrophy type 1 (DM1) is a dominantly inherited multi-system disease caused by expanded CTG repeats in the 3' untranslated region of the dystrophia myotonica protein kinase (DMPK) gene. Similar to other repeat disorders, the expanded trinucleotide repeat is unstable and demonstrates a tendency to increase repeat size with age in affected tissues. DNA mismatch repair system is implicated in somatic instability.
