Derivation of iPSC lines from two patients with autism spectrum disorder carrying NRXN1α deletion (NUIGi041-A, NUIG041-B; NUIGi045-A) and one sibling control (NUIGi042-A, NUIGi042-B).

NRXN1 encodes thousands of splicing variants categorized into long NRXN1α, short NRXN1ß and extremely short NRXN1γ, which exert differential roles in neuronal excitation/inhibition. NRXN1α deletions are common in autism spectrum disorder (ASD) and other neurodevelopmental/neuropsychiatric disorders. We derived induced pluripotent stem cells (iPSCs) from one sibling control and two ASD probands carrying NRXN1α+/-, using non-integrating Sendai viral method. All iPSCs highly expressed pluripotency markers and could be differentiated into ectodermal/mesodermal/endodermal cells. The genotype and karyotype of the iPSCs were validated by whole genome SNP array. The availability of the iPSCs offers an opportunity for understanding NRXN1α function in human neurons and in ASD.

Derivation of iPSC lines from three young healthy donors of Caucasian origin (NUIGi035-A; NUIGi036-A; NUIGi037-A).

The induced pluripotent stem cell (iPSC) technology has offered an unprecedented opportunity for disease modelling and drug discovery. Here we used non-integrating Sendai viral method and derived iPSCs from three young healthy Caucasian donors. All iPSCs expressed pluripotency markers highly and could be differentiated into three germ lineages. They possess normal karyotype which was confirmed by whole genome SNP array. The availability of the healthy control iPSCs offers an opportunity for phenotypic comparison and genome editing for a variety of diseases.

Derivation of two iPSC lines from a sporadic ASD patient (NUIGi033-A) and a paternal control (NUIGi034-A).

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.
