Males are more susceptible to neurodevelopmental disorders including intellectual disability, autism spectrum disorder, and attention...
Triple X syndrome (also called trisomy X syndrome, XXX syndrome, or 47,XXX) is a rare genetic condition where females inherit an extra X chromosome. For some females with triple X syndrome, the third X chromosome can be found in every cell in their body. For others, it is only found i...
