Because of this there is a need to seek morphological markers in order to help diagnose the disease. In order to test the hypothesis that prenatal hormones can affect the sexual dimorphic pattern 2D:4D digit ratio in individual with CAH, the aim of this study was to compare the digit ratio in female and male patients with CAH and control subjects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The 2D:4D ratios in both hands of 40 patients (31 females\u201446, XX, and 9 males\u201446, XY) were compared with the measures of control individuals without CAH (100 males and 100 females).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Females with CAH showed 2D:4D ratios typical of male controls (0.950 and 0.947) in both hands (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). In CAH males the left hand 2D:4D ratio (0.983) was statistically different from that of male controls (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These finding support the idea that sexual dimorphism in skeletal development in early fetal life is associated with differences between the exposure to androgens in males and females, and significant differences associated with adrenal hyperplasia. Although the effects of prenatal androgens on skeletal developmental are supported by numerous studies, further investigation is yet required to clarify the disease and establish the digit ratio as a biomarker for CAH.
