Pituitary hormone deficiency, combined, 2

PROP1-related combined pituitary hormone deficiency (CPHD) is associated with deficiencies of growth hormone (GH); thyroid-stimulating hormone (TSH); the two gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH); prolactin (PrL); and occasionally adrenocorticotropic hormone (ACTH). Most affected individuals are ascertained because of growth failure and failure to thrive starting in infancy or early childhood (approximate age range: 9 months to 8 years). Hypothyroidism is usually mild and occurs in later infancy and childhood. Affected individuals can have absent or delayed and incomplete secondary sexual development with infertility. Untreated males usually have a small penis and small testes. Some females experience menarche, but subsequently require hormone replacement therapy. ACTH deficiency is less common and, when present, usually occurs in adolescence or adulthood.
