Oral-facial-digital syndrome with retinal abnormalities: report of a new case

Ocular colobomata, polydactyly, cleft palate and panhypopituitarism: a new syndrome

We describe a male patient with ocular colobomata, cleft palate, polydactyly, panhypopituitarism and possible craniosynostosis, whom we have followed for 30 years. Although there are some similarities to other documented syndromes, this previously unreported combination of features appears to constitute a new syndrome.

Oro-facial-digital syndrome IX with severe microcephaly: a new variant in a genetically isolated population

We describe four patients, two pairs of siblings, with a somewhat unique oro-facial-digital syndrome. The siblings come from the Navajo population which has undergone several genetic "bottlenecks." Thus, as would be anticipated, this syndrome seems to show autosomal recessive inheritance. The combination of the presence of retinal colobomata and the paucity of digital findings in these patients leads us to believe that their condition is best described as a variant of oro-facial-digital syndrome IX. In addition to retinal colobomata, these patients also show severe microcephaly, mental retardation and short stature.

Oral-facial-digital syndromes: review and diagnostic guidelines

The oral-facial-digital syndromes (OFDS) result from the pleiotropic effect of a morphogenetic impairment affecting almost invariably the mouth, face and digits. Other organ systems can be involved, defining specific types of OFDS. To date, 13 types have been distinguished based on characteristic clinical manifestations. An updated list of these types is provided and recent molecular data are discussed.

Neuropathologic findings in a case of OFDS type VI (Váradi syndrome)

Oral-facial-digital syndrome type VI (OFDS VI) or Váradi syndrome is a rare autosomal-recessive disorder distinguished from other oral-facial-digital syndromes by metacarpal abnormalities with central polydactyly and by cerebellar abnormalities. Histopathologic characterization of the cerebellar abnormalities has not been described previously. We describe the neuropathologic findings in a stillborn, 21-week estimated gestational age (EGA) male fetus diagnosed antenatally with signs of OFDS VI. Autopsy findings included: facial abnormalities, postaxial central polydactyly of the right hand, bilateral bifid toes, and absence of cerebellar vermis with hypoplasia of the hemispheric cortex. Microscopic analysis of the cerebellum demonstrated absence of the subpial granular cell layer and disruption or dysgenesis of the glial architecture. These histopathologic findings suggest that a primary neuronal or glial cell defect, rather than an associated Dandy-Walker malformation, may account for the cerebellar abnormalities in this form of oral-facial-digital syndrome.

Oral-facial-digital syndrome type IX in a patient with Dandy-Walker malformation

We report a girl with oral, facial, and digital anomalies including multiple alveolar frenula, lobulated tongue with nodules, a posterior cleft palate, hypertelorism, a prominent forehead with a large anterior fontanelle, and postaxial polydactyly in both hands and the right foot, features compatible with the oral-facial-digital syndrome (OFDS). In addition, she had bilateral microphthalmia, optic disc coloboma, and retinal degeneration with partial detachment, thus establishing a diagnosis of OFDS type IX. Dandy-Walker malformation and retrobulbar cysts were observed on MRI. These additional malformations have not been reported in OFDS type IX. The frequent apnoeic spells which occurred immediately after birth were relieved after cystoperitoneal shunt implantation for hydrocephalus. Considering our case and previous reports of OFDS type IX, including two male sibs, a boy born to consanguineous parents, and three females, inheritance is probably autosomal recessive.
