| A rare primary bone dysplasia with characteristics of intrauterine growth retardation, pre and postnatal disproportionate short stature with short, rhizomelic limbs, facial dysmorphism, a short neck and small thorax. Hypotonia, cardiomegaly and global developmental delay have also been associated. Several radiographic findings have been reported, including ribs with cupped ends, platyspondyly, square iliac bones, horizontal and trident acetabula, hypoplastic ischia, and delayed epiphyseal ossification. There is evidence this disease is caused by homozygous mutation in the MAGMAS (PAM16) gene on chromosome 16p13. |
