Also known as: De Morsier's syndrome
Septo-optic dysplasia (SOD) has three common features: abnormal development of structures separating right and left halves of the brain, hypoplasia (underdevelopment) of pituitary gland and optic nerves. The pituitary releases hormones (chemical messages) including growth hormone. Those affected may be short, have learning disability, neurological problems and impaired vision. Other pituitary hormones may be affected; those controlling puberty, thyroid stimulating hormone and ACTH, which stimulates release of the stress hormone cortisol and vasopressin that retains water in the body lack resulting in too much urine and dehydration. Diagnosis is based on features and brain imaging. Management may involve growth hormone replacement. Vision aids may be needed. Some rare forms of SOD have been associated with genetic mutations, but most are sporadic (no family history). Affected families should be referred to a genetics centre for information and support.
