Here, we describe a family with four affected members. They all suffer from different diseases: febrile convulsion, epileptic seizures, PKD or headache.
The whole coding region of PRRT2 gene has been analyzed.
Molecular testing revealed the PRRT2 gene mutation c649.delC in exon 2 for all three sibs as well as for the mother.
Our presented family case shows the great variability within PRRT2 linked phenotypes even within the same family. Further and more detailed studies will be needed before genetic findings enter into the daily diagnostic and the daily genetic counseling with all its consequences.
