Night blindness, characteristic facies, and skeletal abnormalities in two brothers.
Two brothers are described with a similar physical appearance characterised by minor periorbital anomalies, malar flatness, a maxillary overbite, retrognathia, sloping shoulders, joint hyperextensibility, and minor radiological anomalies. In addition, they had a slowly progressing night blindness, myopia, and extinguished electroretinograms. The mother had mild expression of some of the physical anomalies and a decreased electroretinogram response to red light. We have been unable to find any report of similarly affected children. The possible modes of inheritance are discussed.
