[英文釋義] The 46,XX gonadal dysgenesis may be sporadic or familial. Familial XX gonadal dysgenesis is transmitted as an autosomal recessive trait and its locus was mapped to chromosome 2. Mutation in the gene for the FSH receptor (RECEPTORS,FSH) was detected. Sporadic XX gonadal dysgenesis is heterogeneous and has been associated with trisomy-13 and trisomy-18. These phenotypic females are characterized by a normal stature,sexual infantilism,bilateral streak gonads,amenorrhea,elevated plasma LUTEINIZING HORMONE and FSH concentration. The syndrome is sometimes called pure gonadal dysgenesis,but this designation may also refer to gonadal dysgenesis with a 46,XY karyotype (GONADAL DYSGENESIS,46,XY).
