Patients who suffer from congenital hypopituitarism display a wide spectrum of phenotypes including pituitary hormone deficiencies and, in some cases, additional extrapituitary manifestations depending on the causative gene. A group of genes underlying hypopituitarism has been identified, yet several of them remain unknown. Here, we identified compound heterozygous variants in the TBC1D32 gene, c.1165_1166dupGT, p.(Gln390Phefs*32) and c.2151delA, p.(Lys717Asnfs*29) in...
