| A rare bone disease and a form of microcephalic primordial dwarfism with characteristics of severe pre and postnatal growth retardation, with marked microcephaly in proportion to body size, skeletal dysplasia, abnormal dentition, insulin resistance and increased risk for cerebrovascular disease. Caused by mutations in PCNT (21q22.3), encoding pericentrin, which anchors a wide range of centrosomal proteins and protein complexes during cell division. Disruption of pericentrin is thought to cause mitotic spindle defects, and impaired cell proliferation. Transmission is autosomal recessive. |
