  1. The nine CLJ-affected Vorderwald × Montbéliarde cattle were scored for the site of cleft lip (SITE), depth of cleft lip (DEPTH), width of cleft lip (WIDTH), changes of the dental plate and hard palate (DEN-HAP), deviation of the face from the midline (DEVIATION), degree of the lateral curvature of the mandibles (CURVATURE), slope of the anterior part of the lower jaw (SLOPE) and bone loss at the proc. nasalis of the os incisivum (INCISIVUM). Score 0 represents no lesions, while increasing scores reflect increasing severity. See Additional file 1 for details on the scoring system. A right-sided minor form and a right-sided major-form of a cleft lip with a vertical dimension <1/2 accompanied cases 4 and 9 with a complete left CLJ. Case 7 with a complete right-sided CLJ had an incomplete cleft lip with a vertical dimension <1/2 on the left side. Animals with a complete right-sided CLJ (cases 1, 2, 3, 5) exhibited the highest degree of deviation of the face including the mandibles. Cases with a complete unilateral CLJ and a minor or major form of cleft lip on either side (cases 4, 7, 9) had a moderate lateral deviation of the face and mandibles. Complete left-sided (case 8) and complete bilateral CLJ (case 6) were associated with the mildest degree of deviation of the face
