J Clin Invest. 2020 Aug 3;130(8):4501–4515. doi: 10.1172/JCI136745. PMID: 32453714.This study used mouse models to investigate the role of LIM homeodomain transcription factor Isl1 in pituitary development. It reveals that Isl1 has multiple, critical roles in pituitary gland development. Pituitary-specific Isl1 deletion caused hypopituitarism with increased stem c...

PMID: 33795686.The authors describe 5 patients with Cardio-Facio-Cutaneous (CFC) syndrome with features of septo−optic dysplasia (SOD), and GH/IGF−1 deficiency of variable degree. All were identified to carry a gain−of−function mutation in BRAF.RASopathies encompass Noonan ...

PMID: 34270938.Brief Summary: This study reports splice-disruptive variants in POU1F1 in 4 families with hypopituitarism and uses a high-throughput splicing reporter assay to create a comprehensive catalogue of such variants in or near exon 2 of the gene. The catalogue paves the way for identifying synon...
