A 17-year-old girl is being evaluated for primary amenorrhea. A pelvic ultrasound shows no uterus, fallopian tubes, or ovaries, despite having normal external sexual organs. On physical examination, there is no axillary or pubic hair, and breast development is normal. The laboratory tests show evidence of increased serum testosterone with normal conversion to dihydrotestosterone (DHT) and increased luteinizing hormone (LH). What is the karyotype of this patient?
