Rhizomelic chondrodysplasia punctata (RCP) is a rare autosomal recessive disorder with many associated medical complications. Prior to this study, natural history information about RCP was limited and based on experiences with small populations of affected individuals. We delineate the natural history of RCP through systematic analysis of 35 previously unreported individuals (as well as review of 62 literature cases with respect to survival and cause of death). Survival, growth, and developmental expectations and medical needs are summarized based upon experience with this population. Survival is greater among this population than previously reported, with 90% surviving up to 1 year and 50% surviving up to 6 years. Cause of death is most often respiratory problem. All infants with RCP have joint contractures, bilateral cataracts, and severe growth and psychomotor delays. Recommendations for health supervision of children with RCP and for parental counseling are presented. © 2003 Wiley‐Liss, Inc.
