Abstract
A term infant had dwarfism with characteristic skeletal and extraskeletal changes of the short rib‐polydactyly syndrome type 2 (Majewski). The skeletal changes included extremely short horizontal ribs, extreme micromelia with disproportionately short ovoid tibiae, and pre‐ and post‐axial polydactyly. Microscopically, cartilage showed markedly stunted and disorganized endochondral ossification. Extraskeletal manifestations were hydrops, cleft lip, malformed larynx with hypoplastic epiglottis, pulmonary hypoplasia, glomerular and renal tubular cysts, ambiguous genitalia, pachygyria and small cerebellar vermis. Parental consanguinity supports the hypothesis of autosomal recessive inheritance of the condition.
