Phacomatoses, genetic testing for personalisation of clinical management (part 2)

Von Hippel-Lindau disease and tuberous sclerosis are rare genetic disorders, which belong to the group of phacomatoses. They involve an increased risk of development of multiple cancers, mostly benign ones, which may undergo malignant transformation. Genetic diagnostic including identification of the pathogenic variant of the VHL and TSC1 and TSC2 genes enables optimisation of patient care and identification of relatives who carry the mutation.
