Background: Cleft lip and/or palate is characterized by failure of fusion between certain embryological processes during facial morphogenesis. Cleft lip and palate is multifactorial in origin, some clefts are caused by single mutant genes, some are due to chromosomal aberrations, and the great majority are caused by interaction of genetic and environmental factors. The aim of the study is to find the relationship between ABO blood group and cleft lip/ cleft palate patients treated in our institution
