Generation of an induced pluripotent stem cell line (DHMCi009-A) from an individual with TUBB2A tubulinopathy.

TUBB2A tubulinopathy is a rare neurodevelopmental disorder with developmental delay, epilepsy, and less frequent malformations of cortical development compared to other tubulinopathies. Peripheral blood mononuclear cells (PBMCs) from a male subject harboring the heterozygous de novo TUBB2A variant c.[743C>T] (p.[Ala248Val]) were reprogrammed to induced pluripotent stem cells (iPSCs) using the CytoTune™-iPS 2.0 Sendai Reprogramming Kit (Invitrogen). Generated iPSCs showed a normal karyotype, expression of pluripotency markers, spontaneous in vitro differentiation in all three germ layers, and are a suitable human disease model to analyze pathomechanisms underlying TUBB2A tubulinopathy and potential therapeutic targets.

Generation of an induced pluripotent stem cell line (DHMCi008-A) from an individual with TUBA1A tubulinopathy.

Variants in different neuronal tubulin isotypes cause severe neurodevelopmental disorders with cerebral malformations accompanied by developmental delay, motor impairment, and epilepsy, known as tubulinopathies. Induced pluripotent stem cells were generated from peripheral blood mononuclear cells from a female subject carrying the heterozygous de novo variant c.[521C > T] (p.[Ala174Val]) in the TUBA1A gene. PBMCs were reprogrammed using the CytoTune™-iPS 2.0 Sendai Reprogramming Kit (Invitrogen) and showed a normal karyotype, expression of pluripotency markers, and spontaneous in vitro differentiation into all three germ layers. The generated iPSCs represent a useful tool to study the pathophysiology of TUBA1A tubulinopathy.

Generation of an induced pluripotent stem cell line (DHMCi007-A) from a patient with autosomal recessive polycystic kidney disease (ARPKD) carrying a homozygous missense mutation in the fibrocystin-encoding PKHD1 gene.

Autosomal recessive polycystic kidney disease (ARPKD) is a severe pediatric kidney disorder primarily caused by mutations in the fibrocystin-encoding PKHD1 gene. It is characterized by the progressive development of cysts, eventually leading to renal failure. In order to create patient specific iPSCs, peripheral blood mononuclear cells (PBMCs) from a female patient carrying a homozygous PKHD1 mutation (c.8285A>T(;)(8285A>T)) were reprogrammed using the non-integral Cytotune®-iPS 2.0 Sendai Reprogramming Kit (Invitrogen). Morphology and karyotype of the cells are normal. Pluripotency hallmarks as well as the potential to spontaneously differentiate into all three germ layers were shown by immunofluorescence staining and RT-PCR.

Generation of an induced pluripotent stem cell line (DHMCi006-A) from a patient with autosomal recessive polycystic kidney disease (ARPKD) carrying a compound heterozygous missense mutation in the fibrocystin encoding PKHD1 gene.

Mutations in the PKHD1 gene, encoding for the ciliary protein fibrocystin, play a major role in the cystogenesis in autosomal recessive polycystic kidney disease (ARPKD), a severe pediatric kidney disorder. Peripheral blood mononuclear cells (PBMCs) from a female patient carrying a compound heterozygous PKHD1 mutation (c.6331A>G(;)7717C>T) were obtained and reprogrammed by viral transduction using the Cytotune®-iPS 2.0 Sendai Reprogramming Kit (Invitrogen). The resulting iPSCs display a normal karyotype, express pluripotency markers, and show the potential for spontaneous differentiation in vitro, offering a useful tool for studying ARPKD pathomechanisms and drug screening.
