KDR and Hodgkins lymphoma: Rotunno et al. in 2016 [9] studied, by whole exome sequencing, 65 families with recurrent HL and found in two families, the only recurrent mutation found until now, a nonsynonymous c.3193G>A change in the KDR gene (kinase insert domain receptor) also known as VEGFR2 (vascular endothelial growth factor receptor 2), since most of the identified variants are “private” for each affected family.
