PMID: 31504653.This paper describes two genes and three syndromes that clinicians would probably like to know when treating patients with a syndromic form of panhypopituitarism. Heterozygous mutation in a maternally imprinted gene, MAGEL2, was described in four patients...

Yes, but it is a newish cilopathy gene in the hedgehog pathway. Hedgehog family of polypeptides (Sonic (Shh), Indian (Ihh) and desert (Dhh) hedgehog) are signaling molecules that are needed for many cellular events and pl...
