摘要
<正>Dear Editor,Microcephalic osteodysplastic primordial dwarfism type II(MOPD II) is characterized by developmental retardation,wherein the affected individuals usually present with intrauterine growth retardation and preterm birth (Majewski et al., 1982; Willems et al., 2010). This leads to an average weight of <1,500 g at birth and extremely restricted postnatal growth (Hall et al., 2004; Rauch, 2011). Clinical manifestations of MOPD II include microcephaly, disproportionately short stature, mild skeletal dysplasia, unusual facial features including a prominent nose, prominent eyes in infancy and early childhood, some affected individuals exhibit slightly reduced intellectual development and cerebral vascular
