27 index patients suspected of having VHL disease from unrelated Chinese families and their relatives were studied. The nucleotide were numbered according to the sequence numbering by Latif et al, 1993 and this was converted to NM_000551.3. The paper did not differentiate between a pancreatic cysts and tumor and presented these together as a 'pancreatic lesion'. The paper summariezed the phenotypes of the families together. Family 7 was found with p.Asn78Thr mutation in the VHL gene: 1/2 members had CNS hemangioblastoma and 2/2 has renal cell carcinoma. ACMG PP4

VariantEvidence: Variant is declared as “c.446A>C (N78T)” by the authors, this was treated as a legacy variant and mapped to c.233A>C, N78T. This study found coexpression of Epo and EpoR in 11 RCCs and in 10 benign renal cysts in a spectrum of VHL renal disease suggesting that Epo/EpoR coexpression is present in both benign and malignant stages of renal neoplasia. Six benign cysts stained for Epo but not EpoR. The researchers detected loss of heterozygosity of a wild-type VHL allele in different RCCs with microsatellite markers, D3S1110 and D3S2452, flanking the VHL gene
