Although MOPD types 1 and 3 were originally described as two separate entities on the basis of radiological criteria (notably small differences in pelvic and long bone structure), later reports confirmed that the two forms represent different modes of expression of the same syndrome. osteodysplastic primordial dwarfism type I microcephalic osteodysplastic primordial dwarfism types 1 and 3 GARD:0005120 Orphanet:2636 microcephalic osteodysplastic primordial dwarfism, Taybi-Linder type primordial microcephalic dwarfism, Crachami type primordial dwarfism and slender bone disorder
