Abstract
Females with a 47,XXX karyotype were first described by Jacobs (1979). The incidence of 47,XXX among female newborns is approximately 1 in 1,000 live births (Pennington et al. 1980). It is the most common female chromosomal abnormality. As some individuals are only mildly affected or asymptomatic, it is estimated that only 10 % of individuals with trisomy X are actually diagnosed (Tartaglia et al. 2010).
