[A clinico-genetic study of patients with congenital deformities of the jaw bones]

Clinical and genetic examination of 78 patients, 43 of these women with jaw bone deformations aged 16 to 30, has revealed that inferior macrognathia combined with superior macrognathia were the most incident in jaw bone deformations. The share of familial cases was 23.9%, this proving a hereditary predisposition to such conditions. These data indicate an etiologic and pathogenetic heterogeneity of patients with deformations of the jaw bones.
