ABSTRACT
Although several studies have demonstrated familial aggregation of nonsyndromic cleft lip with or without cleft palate (CL/P), its model of inheritance remains uncertain. We report the results of complex segregation analysis performed in South American families with a newborn affected with CL/P. Families of 1,792 consecutive newborns affected with CL/P and registered during the period 1967 to 1997 were studied. A model that did not include a major locus was the best-fitting model for CL/P families. This result is in agreement with previous studies which showed a significant association of several putative susceptibility loci and CL/P, indicating that the genes involved in CL/P are likely to have only a very modest impact on disease risk
