Spondylometaphyseal dysplasia with cone-rod dystrophy.
The co-occurrence of ophthalmologic abnormality and intrinsic skeletal dysplasia is uncommon. We describe eight instances of a unique form of spondylometaphyseal dysplasia (SMD) associated with cone-rod dystrophy (although documentation is insufficient to be certain of that diagnosis in some). This is a new, syndromic form of SMD for which there is evidence for autosomal recessive transmission. Recognition of the specific bony features described here should precipitate comprehensive ophthalmologic assessment, since vision impairment becomes significantly disabling with age.
