GH deficiency may also be brought on by mutations in genes that regulate its synthesis and secretion. Affected genes embody PIT-1 (pituitary-specific transcription issue-1) and POUF-1 (prophet of PIT-1). Mutations in these genes may trigger decreased synthesis and secretion of other pituitary hormones. In some cases, GH deficiency is the result of GHRH deficiency, by which case GH secretion could also be stimulated by infusion of GHRH.
