Abstract

Sex typing may become the start point in investigations that are usually performed through amelogenin typing. In cases involving genotype-phenotype discrepancy, amelogenin typing could yield misleading results. The rare XX male syndrome is characterized by a phenotypic male with a 46, XX female karyotype. In this point, this case report would help understand the importance of genotype-phenotype discrepancy.
