<prompt> 46, XY chromosomal pattern with uterus and cervix but poorly developed breasts are seen inSwyer syndromeTurner syndromeAndrogen insensitivity syndromeKlinefelter syndrome  <response>: Complete Gonadal Dysgenesis Swyer SyndromeSwyer syndrome is an uncommon form of gonadal dysgenesis, characterized by a 46, XY karyotype.Despite the presence of a Y chromosome, the phenotype is female because the dysgenetic streak gonads produce neither AMH nor androgens. Consequently, the vagina, cervix, uterus, and fallopian tubes develop normally and the internal and external genitalia do not masculinize but due to hypoestrogenism breasts are poorly developed.Reference: Clinical gynecologic endocrinology; 10th edition; Chapter 9; Normal and Abnormal Sexual Development; Page no: 365
