An azoospermic male with a novel chromosome 46, XX, der(15)t(Y; 15)(p11.3; p12).

ABSTRACT: Male individuals with a 46, XX karyotype are commonly diagnosed with 46, XX male sex reversal syndrome, one of the rarest sex chromosomal anomalies. In this case, we report a rare XX male with Y-specific DNA sequences located near the end of chromosome 15 p-arm, which was verified by fluorescent in situ hybridization (FISH) as well as copy number variation sequencing (CNV-seq) based on the next- generation sequencing method (>100 Kb). To the best of our knowledge, there have been no reports of XX male with the Yp region transferred to the terminal of chromosome 15 short arm.
