Major Features Head and neck: Microcephaly, micrognathia, prognathism triangular face, high sloping forehead, craniosynostosis, narrow bifrontal diameter, dolichocephaly, trigonocephaly, small face and narrow face, brachycephaly, large open fontanels, prominent occiput, prominent glabella, flat occiput, and Robin sequence. Ears: Large or small ears, low-set posteriorly angulated ears, hypoplastic helices, anteverted auricles, prominent lower anthelices, folded helices, cup-shaped ears, hypoplastic tragus, and ear or pre-auricular fistulae. Otitis media is frequent. Eyes: Blepharophimosis, blepharoptosis, telecanthus, hypertelorism or hypotelorism, upslanted or downslanted palpebral fissures, epicanthus, arched eyebrows, strabismus, esotropia, microphthalmia, iris coloboma, nystagmus, anisocoria, megalocornea, iris hypoplasia, oculomotor paralysis, astigmatism, blue sclera, deep optic nerve cupping, immature retinal vessels, and tortuosity of retinal vessels.

The clinic day, held in the Research Center at the University of Utah Hospital, included individual consultations for each attending family with Dr. John Opitz and Dr. Giovanni Neri. In addition, two group conferences (including question/answer sessions) were held for all attendees. The day concluded with a dinner sponsored by the University of Utah Dept. of Genetics. The clinic day was arranged and organized by Alexis Poss, Genetics Couselor. Report Transcript of newspaper article featuring one of our children, published in the Tulsa World, January 6, 1999

      D ubowitz syndrome is a malformation syndrome defined by prenatal and postnatal growth retardation, microcephaly, and a characteristic facial appearance. First described in 1965 by Dr. Victor Dubowitz, the condition was further defined by Dr. John Opitz who proposed the designation Dubowitz syndrome It is present at birth and is thought to be caused by a single defective gene. Neither the location of the gene nor the pathogenesis by which the diverse manifestations are produced are yet known. The condition is not caused by anything the parents did or did not do. It is present in the fetus from the beginning of that individual's development. Originally believed to be very rare, it is now thought that Dubowitz syndrome may not be as rare as it is under-diagnosed. As awareness of the syndrome increases, affected individuals are being diagnosed in greater numbers. It is our hope that this material will help to promote public awareness of the syndrome and provide families and others with easily accessible information in layman's terms.

      First descriptions . . . In 1965, Dr. Victor Dubowitz of the University of Sheffield, England published a paper [31] describing a young girl with pre- and postnatal growth retardation, microcephaly, unusual facial features, and a history of eczema occurring on her face and insides of her knees and elbows. Dr. Dubowitz noted that an older female sibling of the child, who had exhibited a similar facial appearance, had died at 3 months of age. The sister's birth weight had been only 4 lb., and although she had shown no eczema, she did have some webbing between her toes. Based on the similar features of the two siblings, Dr. Dubowitz suggested their condition may represent a distinct and recognizable autosomal recessive syndrome. He went on to compare his patient to a number of other patients described in previous literature, and questioned whether the new condition might represent a variation of a previously described syndrome. In 1971, Dr. John Opitz and Dr. Frank Gross of the University of Wisconsin Medical School, in collaboration with Dr. Robert Gorlin of the University of Minnesota School of Dentistry, published a paper [53] elaborating on the condition described by Dr. Dubowitz through the presentation of three additional patients. Following intensive study, Dr. Opitz concluded that the condition was a distinct and unique genetic syndrome, and proposed the designation of
