The Headlines Family Weekend is our main event, which we host annually and generally runs from Saturday morning to Sunday lunch time. Detailed phenotypic analysis in these families showed that females were more severely affected than males; affected males showed hypertelorism as the only sign, and none had coronal synostosis in contrast to the findings in their female relatives.
