Retinal detachment and cataract, facial dysmorphism, generalized osteoporosis, immobile spine and platyspondyly in a consanguinous kindred--a possible new syndrome.
We report on a consanguineous family with 6 children (out of 7) affected by a spondylo-ocular syndrome. Clinical features include cataract, loss of vision due to retinal detachment, facial dysmorphism, facial hypotonia, normal height with disproportional short trunk, immobile spine with thorakal kyphosis and reduced lumbal lordosis. On ophthalmological examination of the index patient, a dense cataract and complete retinal detachment could be detected on the right eye. On the left eye, an absent lens nucleus was found, but no retinal detachment. On radiological examination, there was generalized moderate osteoporosis; the spine showed marked platyspondyly and the bone age was advanced. On laboratory investigations, a normal excretion of amino acids, mucopolysaccharides and oligosaccharides could be found. The phenotypical spectrum observed in the 6 affected individuals was rather uniform. The karyotype was normal in all affected children. This hitherto undescribed combination of oculo-skeletal symptoms shows most resemblance with connective tissue disorders, suggesting a range of candidate genes for mutation analysis.
