Progressive familial heart block (type I) has been identified in the RSA. Since 1977 many families have been referred for pedigree tracing. The present probands of some 9 pedigrees are the descendants of specific children of an immigrant; other genetic diseases appear in these pedigrees. The necessity of identifying, diagnosing and possibly treating the descendants of carriers is emphasized.
