title: Third case of cerebral, ocular, dental, auricular, skeletal anomalies (CODAS) syndrome, further delineating a new malformation syndrome: first report of an affected male and review of literature.
abstract: CODAS syndrome (MIM# 600373) is a rare multiple congenital anomalies syndrome. The disorder is highly distinctive with characteristic features consisting of developmental delay, cataracts, unusual enamel projections, overfolded and crumpled ears, epiphyseal dysplasia, and dysmorphic features (grooved nose, ptosis). To date, there have been two affected female children reported. The first was a Canadian girl of Mennonite descent, reported by our group, and the second was a girl from Brazil. The etiology and pattern of inheritance of CODAS is unknown. Herein we report a third affected child, a Canadian male infant of Mennonite ancestry. The child, now two years old, exhibits ptosis, cataracts, overfolded ears, grooved nasal tip, dental projections, developmental delay, and characteristic skeletal anomalies. The findings are characteristic for CODAS syndrome. All investigations including karyotype, metabolic screening, peroxisomal studies, and studies of cholesterol biosynthesis were normal. The underlying defect responsible for CODAS syndrome remains unknown. Many of the features suggest a possible underlying collagen gene defect. The fact that this child is the second child from the Manitoba Mennonite community, a genetic isolate, suggests the possibility of autosomal recessive inheritance. To date, there has not been a familial recurrence.
