194C>T Ser65Leu Germline mutation
Tissues embedded in paraffin blocks were collected from 203 cHAB patients operated in different Medical Centres in Poland. Eight of these harboured germline mutations in unrelated patients from distinct undiagnosed VHL families. Various variants were unverified as somatic or germline as they were detected in tumour but blood samples were not tested. Other phenotypes and demographic information is not known. Patient 30 was found with a germline p.Ser65Leu mutation in the VHL gene. This patient also had a somatic mutation (c.266T>C p.Leu89Pro) in the tumour.
