Submicroscopic duplications involving SOX3 and/or its flanking regions have been identified in 46,XX individuals both with and without disorders of sex development, raising the question whether SOX3 overdosage is sufficient to induce testicular development in genetically female individuals. Here, we report a mother-daughter pair with female phenotypes and random X inactivation. The individuals carry complex X chromosomal rearrangements leading to a copy number gain of genomic regions involving SOX3 and its upstream region. The amplified DNA fragments were detected at Xq27. These results provide evidence that SOX3 overdosage permits normal sex development in 46,XX individuals with random X inactivation. (C) 2015 S. Karger AG, Basel
