Spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL): A Brazilian case

Abstract
This is a report on a Brazilian patient with spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL; MIM 271640), a rare autosomal recessive skeletal dysplasia characterized by dwarfism, articular hypermobility, progressive intractable spinal malalignment, a typical facies and a propensity to joint dislocation and subluxation. The condition has been described only in 20 children of Afrikaans-speaking parents in South Africa. This is the first report of a non-Afrikaans patient with this genetic entity.
