Unique case of growth hormone (GH) deficiency accompanied by clinical anophthalmia, hypoplastic orbits, digital dysplasia, short stature, obesity, and diabetes mellitus.

A 43-year-old female was admitted to our hospital for polydipsia and hyperglycemia. She had total blindness and globes were not recognized by inspection, indicating clinical anophthalmia. Physical examination revealed short stature, obesity, prematurely gray hair, shortness of fingers and toes, syndactyly, and multiple dental caries. Laboratory examination showed hyperglycemia, increased glycosilated hemoglobin (HbA1c) and insulin resistance on euglycemic glucose clamp. Blunted growth hormone (GH) secretion was shown in response to insulin-induced hypoglycemia, arginine infusion, and GH-releasing hormone (GHRH) loading test, and in 24 h spontaneous GH profile. Magnetic resonance imaging (MRI) and computed tomography (CT) showed dysostosis of orbit, defect of optic nerve, enlarged suprasellar cistern, and prolonged pituitary stalk. This may be the first report of a unique case with GH deficiency accompanied by clinical anophthalmia, hypoplastic orbits, digital dysplasia, short stature, obesity, and diabetes mellitus.

Anophthalmia-Waardenburg syndrome: a report of three cases.

We report on 2 Turkish families with children who had bilateral anophthalmia, upper and lower limb abnormalities, mental retardation and consanguineous parents. We have evaluated the 2 cases in the first family and the only case in the second as anophthalmia-Waardenburg syndrome. This is an extremely rare autosomal recessive syndrome.

Anophthalmia, intracerebral cysts, and cleft lip/palate: expansion of the phenotype in oculocerebrocutaneous syndrome?

We report on a patient with multiple congenital anomalies including anophthalmia, cleft lip and palate, and central nervous system anomalies similar to the case reported by Leichtman et al. [1994: Am J Med Genet 50:39-41] and to oculocerebrocutaneous (Delleman) syndrome. Although the two cases and those with oculocerebrocutaneous syndrome may represent separate but overlapping entities, our patient and the case described by Leichtman et al. [1994: Am J Med Genet 50:39-41] may represent a more severe form of oculocerebrocutaneous syndrome.

Anophthalmia-microphthalmia-oblique clefting syndrome: confirmation of the Fryns anophthalmia syndrome.

We describe a patient with bilateral extreme microphthalmia with bilateral congenital glaucoma, bilateral medial oblique facial cleft ending in lid colobomas, bilateral stenosis of the choanae, bifid uvula, frontal encephalocele, and premature craniosynostosis. The cause is unknown, but the phenotype resembles the Fryns anophthalmia-plus syndrome, which may be a recessive trait, although intrauterine environmental factors cannot be excluded.

New syndrome of growth and mental retardation, structural anomalies of the central nervous system, and first branchial arch, anophthalmia, heminasal a/hypoplasia, and atypical clefting: report on four Brazilian patients.

We report on four unrelated Brazilian patients with growth and mental retardation, structural anomalies of the central nervous system (CNS), mainly callosal agenesis, prominent forehead, facial asymmetry, anophthalmia, heminasal a/hypoplasia, preauricular skin tags, structural anomalies of the external ears, and atypical clefting. This combination of anomalies is unique and, to our knowledge, is a previously undescribed syndrome of unknown etiology, although one of the patients was born to a consanguineous couple, suggesting the possibility of autosomal recessive inheritance. Clinical, genetic, and differential diagnosis aspects are discussed.

Ophthalmo-acromelic syndrome: report and review.

The ophthalmo-acromelic syndrome of Waardenburg is an autosomal recessive trait comprising eye malformations ranging from true anophthalmia to mild microphthalmia with acromelic malformations. Some 29 affected individuals have been reported since Waardenburg's first report in 1935 [Waardenburg et al., 1961]. We report on a new case with bilateral anophthalmia and typical limb malformations. The patient also was found to have interruption of the inferior vena cava with azygos continuation as an additional finding. The previous reports are reviewed to elucidate the spectrum of the syndrome.

Sibs with anencephaly, anophthalmia, clefts, omphalocele, and polydactyly: hydrolethalus or acrocallosal syndrome?

Major characteristics of the acrocallosal syndrome include severe mental retardation, agenesis or hypoplasia of the corpus callosum, and polydactyly of fingers and toes. In the past few years, anencephaly has also been noted, together with other midline defects. We report on a nonconsanguineous, Norwegian couple with a history of two pregnancies with a male and a female fetus, respectively, with anencephaly, median cleft lip and palate, omphalocele, and preaxial polydactyly, suggesting the diagnosis of the acrocallosal syndrome. Both fetuses also lacked eyes and nose, a finding not previously reported in the acrocallosal syndrome. Microphthalmia has been reported in the hydrolethalus syndrome, which may be caused by mutations in the same gene as the acrocallosal syndrome. The present report adds support to the hypothesis that the acrocallosal and hydrolethalus syndromes may be allelic conditions. The family history is consistent with autosomal recessive inheritance.

Developmental toxicity of the HIV-protease inhibitor indinavir in rats.

BACKGROUND: Indinavir is an antiviral agent used for the treatment of HIV infection. We studied its developmental toxicity in rats. METHODS: Pregnant animals were treated orally with 500 mg indinavir/kg body weight (bw) from day 6 to 15 of gestation (once daily) or from day 9 to 11 (twice daily). Fetuses were evaluated for external and skeletal anomalies on day 21 of gestation. In addition, 19 rats were treated from day 9 of gestation to day 24 postnatally with 500 mg indinavir/kg bw once daily; a control group of 17 rats was treated with the vehicle accordingly. Developmental landmarks were recorded. Sixteen offspring each were studied on postnatal days 7, 14, 21, and 35 for hepatic enzyme activity. Liver tissue was examined by electron microscopy. RESULTS: Fetal examination on day 21 of pregnancy showed no treatment-related effects on number, weight, and viability of the fetuses; however, an increased incidence was noted in the supernumerary ribs and variations of the vertebral ossification centers in both indinavir-treated groups. Postnatal evaluation showed delayed fur development, eye opening, and descensus testis. The most striking finding was unilateral anophthalmia, observed in 7 pups (3%) from 2 out of 19 litters exposed to indinavir, but not in controls. Only minor changes in hepatic monooxygenase activities occurred in dams. Electron microscopy of liver samples showed hepatocellular inclusions of lipids and myelin figure-like structures in maternal livers and infiltration with granulocytes in offspring livers. CONCLUSIONS: Further studies on reproductive toxicity, including combinations of three or more antiretroviral agents as used therapeutically, are needed to determine the hazards of such a treatment.

Effects of pinealectomy on reproduction in the Syrian hamster mutant anophthalmic white (Wh).

The gene Wh, causing anophthalmia in the Syrian hamster, Mesocricetus auratus, is a pleiotropic gene affecting eye development, pigmentation, hearing, and reproduction. Male hamsters homozygous for this gene are usually sterile. Since both Wh and the pineal organ are known to suppress reproductive function, the objective of this study was twofold: (1) to determine whether Wh, by itself, influences testicular differentiation; and (2) to determine whether removal of the pineal gland will restore fertility to both experimentally blinded (B), genetically normal [wh/wh(B)] hamsters and mutant, eyeless (Wh/Wh) hamsters. Accordingly, one testis from each of ten wh/wh(B) and ten Wh/Wh hamsters at approximately 60 days of age was removed, and these testes were compared at the gross and light microscopic level. Since all testes were identical at 60 days of age and contained normal differentiating germ cells, the gene Wh does not appear to affect initial testicular differentiation. Testicular tissues from at least ten wh/wh, wh/wh(B), heterozygous (Wh/wh), and Wh/Wh hamsters, at 135 days of age, were also compared. Testes from all wh/wh(B), and 70% of the Wh/Wh hamsters were hypoplasic and aspermic. Approximately 30% of the testes from Wh/Wh hamsters contained some seminiferous tubules with normal sperm present. Pinealectomy fully restored adult testicular size and morphology in all wh/wh(B) and Wh/Wh hamsters. Thus, it was demonstrated that the atrophy of testes from Wh/Wh individuals is a pineal-mediated phenomenon due to failure of eye development and the subsequent lack of a functional visual pathway. Testes from Wh/Wh hamsters appear to be completely competent to respond to the normal, antigonadotrophic effects of the pineal.

Exclusion of SIX6 hemizygosity in a child with anophthalmia, panhypopituitarism and renal failure.

We report a patient who presented with anophthalmia, panhypopituitarism, early onset of end stage renal failure, and craniofacial abnormalities. MRI at age 3 revealed that the pituitary was absent and renal biopsy demonstrated nephronophthisis as the cause of the renal failure. A similar syndrome has been associated with interstitial deletions of chromosome 14q22 and in one case hemizygosity for SIX6 was demonstrated. The patient reported here had a normal karyotype and Southern blot did not reveal loss of one copy of SIX6. We discuss other possible candidate genes that could be implicated in this syndrome.

Combination of diaphragmatic eventration and microphthalmia/anophthalmia is probably nonrandom.

Two sporadic cases of eventration of the diaphragm are reported; one had bilateral colobomatous microphthalmia and the other had anophthalmia. Absence of polydactyly and presence of eventration rather than diaphragmatic hernia helped to exclude Fryns syndrome. These cases together with published cases with overlapping features support the thesis that this combination of defects is nonrandom and of heterogeneous cause. Some cases are due to a pleiotropic gene defect. In other cases, a polytypic developmental field involving an unknown developmental cascade common to the eye and diaphragm may provide a basis for the combination.

Bilateral anophthalmia, esophageal atresia, and right cryptorchidism: a new entity?

We report on a child with bilateral anophthalmia, esophageal atresia, and cryptorchidism. This is the first case observed in the Spanish Collaborative Study of Congenital Malformations (ECEMC) with this constellation of congenital anomalies, and it is similar to that described in 1988 by Rogers. We think that it may constitute a new syndrome.

Mental retardation, structural anomalies of the central nervous system, anophthalmia and abnormal nares: a new MCA/MR syndrome of unknown cause.

We report on 2 unrelated Brazilian girls, born to nonconsanguineous parents, and presenting structural central nervous system defects, hydrocephaly, macrocephaly, craniosynostosis, prominent forehead, anophthalmia, and abnormal nares. These patients may have a previously undescribed recurrent-pattern cerebro-oculo-nasal syndrome.
