Somatotype of children with gonadal dysgenesis and structural anomalies of genitalia.

The somatotype of 92 children with sexual structural anomalies of whom 28 with female Turner's syndrome, 22 with Klinefelter's syndrome, 20 with adreno-genital syndrome, 14 with hypospadias, 2 with Reinfenstein's syndrome and 6 with feminizing testis was established on the basis of biometric and genetically determined morphologic characteristics (dermatoglyphics, pigment complex). A morphogram utilizing 12 anthropometric and 5 dermatoglyphic parameters was constructed; it can be used in phenotypical differentiation of the anatomo-clinical variants of structural anomalies of the genitalia and gonads. The 12 anthropometric parameters were: weight, stature, height of the head + neck segment, the sternum-symphysis distance, length of arms and legs, the biacromial and bitrochanterian diameters, the circumference of the thorax, abdomen, hips and head. The dermatoglyphic parameters were: the digital delta index, TFRC, a-b ridge count, the ATD angle and the A line obliquity. For longitudinal assessment of the phenotype of children with structural anomalies of genitalia and gonads, the authors propose utilization of the percentile diagrams regarding weight, stature, pubes to floor distance, and the biacromial and bitrochanterian diameters.
