Case: F, 16Y0M, Ethnicity Unknown

DiseaseAssertion: retinal capillary hemangioma

FamilyInfo: N/A - family history was unremarkable. The paper states however that this patient inherited the duplication from a nonsymptomatic parent.

VariantEvidence: Quantitative Southern blot/real-time quantitative PCR analyses was normal in this patient. Known polymorphic variant on the 3’UTR of the VHL gene, as well as the 5’UTR. PCR–RFLP assay approach showed that both alleles were expressed in apparently equimolar amounts (Fig. 2d) suggesting that the 11 bp duplication has no effect on expression of the affected allele.
