In a study of 426 unrelated VHL patients, 111 were discovered to have alterations in the VHL gene. 18 novel variants were identified in VHL patients, but none were present in 200 unaffected control individuals. DNA samples from peripheral blood leukocytes underwent polymerase chain reaction (PCR) amplification, denaturing high-performance liquid chromatography (DHPLC), and direct sequence analysis of the entire coding sequence and intron-exon boundaries. This novel, missense mutation was found in a 16 yr old VHL patient with pheochromocytoma (index case 55). Variant was transmitted from a parent (both parents were analyzed) but it is unclear which parent was positive for the variant.
