germline missense mutation at nucleotide 505 (T to C) of the VHL tumor suppressor gene in 14, apparently unrelated, VHL type 2A families from the Black Forest region of Germany.
GroupID/ KindredID: VHL 2
DiseaseAssertion: assumed VHL
GroupSize: 3
GroupNumberMales: N/A
GroupNumberFemales: N/A
GroupEthnicity: German
GroupAgeRange: N/A
FamilyInfo: 3 affected members belong to this VHL type 2A family. One representative affected member was analyzed with this mutation, and VHL was diagnosed clinically in this index person. It is unclear as to whether the additional patients had this precise mutation, although assumed.
GroupPresentingHPOs: HP:0009711; HP:0002666 (retinal capillary hemangioma, pheochromocytoma)
GroupHPOFreeText: all 3 individuals had Pheos, whereas only 1 person had a retinal capillary hemangioma.
