Summaries for Septooptic Dysplasia

UniProtKB/Swiss-Prot : 71 Growth hormone deficiency with pituitary anomalies: A disease characterized by low or absent growth hormone levels, in the presence of a hypoplastic anterior pituitary lobe and ectopic or absent posterior pituitary lobe. Pituitary hormone deficiency, combined, 5: Combined pituitary hormone deficiency is defined as the impaired production of growth hormone and one or more of the other five anterior pituitary hormones. CPHD5 is characterized by complete or partial deficiencies of growth hormone, thyroid-stimulating hormone, luteinizing hormone, follicle stimulating hormone and adrenocorticotropic hormone. Septooptic dysplasia: A clinically heterogeneous disorder defined by any combination of optic nerve hypoplasia, pituitary gland hypoplasia with panhypopopituitarism, and midline abnormalities of the brain, including absence of the corpus callosum and septum pellucidum.

MalaCards based summary : Septooptic Dysplasia, also known as septo-optic dysplasia, is related to hesx1-related combined pituitary hormone deficiency and septo-optic dysplasia spectrum, and has symptoms including short stature, global developmental delay and agenesis of corpus callosum. An important gene associated with Septooptic Dysplasia is HESX1 (HESX Homeobox 1). The drugs Hormone Antagonists and Hormones have been mentioned in the context of this disorder. Affiliated tissues include pituitary, brain and skin, and related phenotypes are endocrine/exocrine gland and growth/size/body region

NINDS : 51 Septo-optic dysplasia (SOD) is a rare disorder characterized by abnormal development of the optic disk, pituitary deficiencies, and often agenesis (absence) of the septum pellucidum (the part of the brain that separates the anterior horns or the lateral ventricles of the brain). Symptoms may include blindness in one or both eyes, pupil dilation in response to light, nystagmus (a rapid, involuntary to-and-fro movement of the eyes), inward and outward deviation of the eyes, hypotonia (low muscle tone), and hormonal problems. Seizures may also occur. In a few cases, jaundice (prolonged yellow skin discoloration) may occur at birth. Intellectual problems vary in severity among individuals. While some children with SOD have normal intelligence, others have learning disabilities. Most, however, are developmentally delayed due to vision impairment or neurological problems.

Genetics Home Reference : 25 Septo-optic dysplasia is a disorder of early brain development. Although its signs and symptoms vary, this condition is traditionally defined by three characteristic features: underdevelopment (hypoplasia) of the optic nerves, abnormal formation of structures along the midline of the brain, and pituitary hypoplasia.

OMIM : 54
Septooptic dysplasia is a clinically heterogeneous disorder loosely defined by any combination of optic nerve hypoplasia, pituitary gland hypoplasia, and midline abnormalities of the brain, including absence of the corpus callosum and septum pellucidum (Dattani et al., 1998). The diagnosis of this rare congenital anomaly is made when 2 or more features of the classic triad are present. Approximately 30% of patients have complete manifestations, 62% display hypopituitarism, and 60% have an absent septum pellucidum. The disorder is equally prevalent in males and females and is more common in infants born to younger mothers, with a reported incidence of 1 in 10,000 live births (summary by Webb and Dattani, 2010). Also see 516020.0012 for a form of septooptic dysplasia associated with cardiomyopathy and exercise intolerance. (182230)

Disease Ontology : 12 An autosomal genetic disease characterized by the classical triad of optic nerve hypoplasia, pituitary gland hypoplasia and midline brain defects that has material basis in mutation in the HESX1 gene on chromosome 3p14.
