Analysis of AMEL-Y Null Allele Caused by Deletion Fragments within the Yp11.2 Region in a Chinese Population

AMEL-Y null allele can lead to misjudgment in sex determination. In practical situations, analysis of other Y chromosome genetic markers that are also located in the Yp11.2 region can be valuable for verifying locus deletion and determining the deletion range. Furthermore, the use of combined multimarker detection represents a trend for gender determination in individual identification, particularly in cases where the AMEL-Y null allele is present.
