A pair of monozygotic, adolescent twins is discordant for sex. The phenotypic female twin has chromosome constitution of 46, XY/45, X. She displays many signs of Turner's syndrome, including typical facies, webbed neck, malformed left kidney, high plasma gonadotropins, and streak ovaries. However, her height is 154 cm which exceeds the height usually reported in Turner's syndrome. The male twin has a karyotype of 46, XY and normal sexual development. Only two other reports of pairs of monozygotic twins of opposite sex have been published.
一对同卵青春期双胞胎的性别不一致。表型为女性的双胞胎染色体组成为46, XY/45, X。她表现出许多特纳综合征的体征，包括典型面容、蹼颈、左肾畸形、血浆促性腺激素水平升高和条索状卵巢。然而，她的身高为154厘米，超过了特纳综合征通常报道的身高。男性双胞胎的核型为46, XY，性发育正常。关于异性同卵双胞胎的报道仅有另外两篇。
