Some 137 patients with thalidomide embryopathy have been registered. Of them, 65 were male and 72 female. The age of patients who had a medical examination from 1976 to 1983, ranged from 7 to 22 years. The mean age was 17.0 ± 2.3 (mean ± SD) years. The number of hearing impairments were 35 (25.6%), limb defects were 55 (40.1%) and combined defects were 47 (34.3%). In order to determine the mutual relationships of 34 abnormal symptoms, the correlation coefficient was calculated, and cluster analysis was carried out by utilizing the result. There was a strong inverse correlation between deformities and hearing impairments. The 34 symptoms were divided into three groups. In the first group 11 symptoms were included, but there was little mutual relationship. Fifteen symptoms belonged to the second group, which evidenced strong mutual relationships. The 8 symptoms belonging to the third group were central to all of the symptoms.
