Spondyloepimetaphyseal dysplasias (SEMDs), predominantly associated with disproportionate short stature, comprise a heterogeneous group of autosomal-dominant, autosomal-recessive, and X-linked recessive skeletal dysplasias caused by pathogenic variants in several genes. Here we characterize a distinct form of skeletal dysplasia in 4 individuals from 3 unrelated Emirati families. Through whole exome sequencing, we identify a novel homozygous missense variant (c.1376A>C; p.As...
