title: Ivemark syndrome in siblings.
abstract: A family in which two brothers have the Ivemark syndrome is reported, thus bringing to eight the total number of families reported with multiple affected siblings. Study of 4059 autopsies, performed over 21 years at a major pediatric referral hospital, identified 32 cases of Ivemark syndrome. All were isolated occurrences in the families. One of six families which provided complete pedigree information was found to be consanguineous. This brings to four the number of reported consanguineous families with Ivemark syndrome. The male excess of affected with Ivemark syndrome is found both for the families with multiple affected siblings and for autopsy-identified cases. These data suggest a recessive inheritance of Ivemark syndrome with male predisposition.
