As of 2008 this syndrome has only been reported in five individuals within three generations of the same family; two young children, their mother, their uncle and their maternal grandmother. This most recent generation to be diagnosed with Ramos-Arroyo syndrome supports the hypothesis that this disease is a distinct autosomal
dominant disorder. If this syndrome could be identified in other families it may help to discriminate the gene responsible.[2]
