The goal of this registry is to collect information on individuals with Microcephalic Osteodysplastic Primordial Dwarfism Type II (also called MOPDII) and other forms of microcephalic primordial dwarfism. The registry will enable detailed natural history studies of MOPD II and associated conditions. The study team hopes that identification of risk factors will allow for preventative treatments and thus a better quality of life for individuals with these diagnoses.~This study is limited to chart review, after signed informed consent obtained.
