Human corticotropin releasing hormone gene is located on the long arm of chromosome 8.

The chromosomal locus of the human corticotropin releasing hormone (hCRH) gene was assigned to chromosome 8 using Southern blot analysis of human x rodent cell hybrids and was localized to band 8q13 using in situ hybridization to metaphase chromosomes. The absence of secondary hybridization strongly suggests that hypothalamic and placental CRH are transcribed from the same gene.
