Sci Rep. 2021 Nov 3;11(1):21590. doi: 10.1038/s41598-021-00939-7. PMID: 34732776.Brief Summary: This study describes the molecular and electrophysiological analysis of the cerebral network generated from cerebral organoids from human induced pluripotent stem cells (hiPSCs) on a patient with neonatal diabetes mellitus due to a KCNJ11 mutation. Some patients w...

To read the full abstract: Pediatr Diabetes. 2018 May;19(3):388-392Mutations in FOXP3 are associated with a severe, early-onset, autoimmunity syndrome known in males known as IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked; OMIM [Online Mendelian Inheritance in Man] 304930). The gene maps to chromosome Xp11.23 and encodes a 431–amino acid protein, also named &#8216...
