[Clinical picture in patients with 46,X,i(Xq) karyotype. Are there differences from Turner syndrome?].

Clinical presentation in 2 patients with 46,X,i(Xq)-Karyotype are described. In both cases no mosaicism could be detected. The two patients show the classical features of gonadal dysgenesis: short stature, sexual infantilism and primary amenorrhea due to streak ovaries. Other characteristic somatic manifestations of the Turner syndrome such as webbing of the neck, however, were missing. In one of the two cases a Hashimoto's thyroiditis was present, which has been repeatedly reported before in the literature in cases with 46,X,i(Xq)-karyotype.
