NCIt definition : Human TBX19 wild-type allele is located in the vicinity of 1q24.2 and is approximately
34 kb in length. This allele, which encodes T-box transcription factor TBX19 protein,
plays a role in the activation of POMC gene expression and the repression of CGA and
TSHB gene expression. Mutations in this gene are associated with isolated adrenocorticotropic
hormone (ACTH) deficiency.;
