Wales and Quarrell described a sister and brother from a consanguineous mating in whom septooptic dysplasia was present, sept mendelian inheritance. Stevens and Dobyns reported a boy with optic nerve hypoplasia, pituitary dysfunction, and MRI findings consistent with septooptic dysplasia, who also had multiple limb defects suggestive of amniotic bands. Septo-optic dysplasia SOD optiac, also referred to as de Morsier syndrome, is a rare congenital condition, characterized by two of the classic triad features: Of the 4 patients diagnosed by the endocrinologist, 2 also had a great delay in diagnosis due to a lack of knowledge about the syndrome by the specialists.

The female was born with dislocation of the hip and talipes equinovarus. One of the cases, although extensively monitored by a multidisciplinary team, never had been evaluated by an endocrinologist until the age of It is rare for siblings to present with identical features of the septo-optic dysplasia spectrum.

Physical examination revealed a cm-tall boy srpto normal findings at a general medical examination. Ophthalmologists and neurologists should be aware to the identification of any of the features of the syndrome, forwarding these patients early to the pediatric endocrinologist, since the pituitary deficiencies may be present since the neonatal period or can appear throughout life, originating permanent sequelae.


Pituitary hormone deficiency, combined, 3. Some additional modality dependent features may also be visible. Septo-optic dysplasia associated with see-saw nystagmus. HESX1 mutations are an uncommon cause of septooptic dysplasia and hypopituitarism. In utero exposure to cocaine and other street drugs can lead to septo-optic dysplasia.

Nonfamilial patients with either septooptic dysplasia patients or isolated pituitary dysfunction, optic nerve hypoplasia, or midline neurologic abnormalities patients originally screened by SSCP were rescreened by heteroduplex detection for mutations in the coding and regulatory regions of HESX1.

There is no recognised gender predilection. When nystagmus develops, it typically appears by 1—8 months of age, and usually indicates that there will be a significant degree of visual impairment, but the severity is difficult to predict in infancy.

Congenital absence of septum dsplasia. In addition, direct sequencing of HESX1 was performed in patients with familial hypopituitarism from 66 unrelated families and in 11 patients born to consanguineous parents.

In three cases 3, 4 and 5the MRI detected the anomaly on the optic tract, with diffused hypoplasia of the chiasm and optic nerve. This investigation still has not been done. Pituitary hormone deficiency, combined, 6.

It could be a causative factor or only secondary to a common etiopathogenic process Opica patient was diagnosed by the genetics service case 1 and the others by the endocrinology clinic.

Valproate toxicity in utero has been implicated as a possible etiology of septo-optic dysplasia.
