Too much diversity and an ever increasing number of genetic disorders appear as a big challenge in the coming future. One of the main sources of genetic disorders is the consanguineous marriages which are, unfortunately, very common in our society.
In order to prepare ourselves to accept the challenges regarding congenital mal-formations due to consanguineous marriages, the first step is to get complete information of their prevalence and their risk factors.
The study was made during 2003-2007 in the city of Tabriz, Iran. We selected 6000 families and data was obtained via a questionnaire comprised of information including marital ages, number of pregnancies, type of delivery, ratio of consanguineous and non consan-guineous marriages, jobs of parents, and effects on child malformations
Consanguineous marriages of all types were related with increased congenital mal-formations (with ratio 43/1000 for consanguineous marriages and for non consanguineous marriages 28/1000). Mother age less than 18 and more than 35 particularly was accompa-nied with increased malformations while education of mother came out to be inversely related to congenital malformation
Increased stillbirths, consanguineous marriage and malformations, especially of musculoskeletal system, require new planning on a national level to control and inform peo-ple of the consequences of consanguineous marriages.
