High incidence of Y-chromosome microdeletions in gonadal tissues from patients with 45,X/46,XY gonadal dysgenesis.
A higher incidence of Y-chromosome microdeletions was found on gonadal DNA than on peripheral blood lymphocyte DNA and on streak gonads than on dysgenetic testis in 11 patients with 45,X/46,XY gonadal dysgenesis. It is probable that an association between Y-chromosome microdeletions and severity of the phenotype in 45,X/46,XY patients exists.
