The aetiology of 46,XY gonadal dysgenesis can be caused by mutations in the genes involved in testis. 17 nov. Destas, 21 (20,2%) apresentavam uma constituição 46,XY. Cinco pacientes ( 26,3%) apresentavam disgenesia gonadal pura XY (DGP XY). El síndrome de Swyer es una disgenesia gonadal pura, con cariotipo 46XY, fenotipo femenino normal, y ausencia completa de tejido gonadal funcionante, que.

Diagnostic methods Diagnosis requires an evaluation of hormonal status gonadal and adrenallaboratory investigations to screen for infectious or autoimmune disorders, karyotype analysis, molecular pua and sometimes laparoscopy with biopsy of ovarian tissue. Inactivating FSHR mutations are inherited in an autosomal recessive manner, BMP15 mutations are inherited in an X-linked manner and NR5A1 mutations disfenesia autosomal dominant in the great majority of cases.
