Abstract
Limb‐body wall complex is a malformation of body and limbs with craniofacial defects. We describe here the epidemiology of this complex using the population‐based registry data in the Kanagawa Birth Defects Monitoring Program during the period 1982–1991. Eleven infants (11/428,599 births) with the complex were ascertained in the study. The incidence and spectrum of the defects observed in our cases were similar to those of other studies. The parental ages in the study group were not significantly different from those in the general population. No teratogenic agents and factors were identified in the present study. Most cases were diagnosed prenatally.
