Therefore, it has been classified as a Variant of Uncertain Significance. Several studies have shown that the VHL protein created from a downstream methionine located at codon 54 is biologically active, and exhibits properties similar to the full-length, wild-type protein (PMID: 9671762, 9751722). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 953371). This variant has not been reported in the literature in individuals affected with VHL-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu46Aspfs*78) in the VHL gene. It is unclear whether it will result in an absent or disrupted protein product because an in-frame methionine located at codon 54 has the potential to rescue this variant. |
