[Association of the ABO blood group system and hip joint dysplasia].

On the basis of distribution of ABO blood groups among 963 sick children with dysplastic pathology of hip joint and 1402 Georgians from among the total population of the city of Tbilisi there have been obtained significant associations of 0 group with this pathology. The hypothesis about genetic community of these symptoms has been rejected. Phenotypic correlations have demonstrated that 0 group of blood promotes an expression of hereditary predisposition to the hip joint dysplastic pathology. Predisposition to this pathology is increased in case of coincidence of 0 group in the patient's mother and in the patient himself.
