VHL c.154G>A

NM_000551.3:c.154G>A (p.Glu52Lys) has a GroupMax filtering allele frequency of 0.08611% (0.0008611) in gnomAD v4.1, which exceeds the VHL VCEP BA1 stand-alone benign threshold of 0.0156% (0.000156).1 The variant is observed in 107 of 1,583,178 alleles in gnomAD v4.1, including 1 homozygote, with highest frequency in the African/African American population (78/74,388 alleles, 0.1049%).2 BA1 as stand-alone benign is independently sufficient to classify the variant as Benign regardless of other evidence criteria.3 BS1 is also met at strong benign level: gnomAD v4 GroupMax FAF 0.0008611 exceeds the VCEP BS1 threshold of 0.0000156.4 BP4 is met at supporting benign level: SpliceAI predicts no splicing impact (max delta = 0.00).5 The variant was observed in 1-2 VHL families (Olschwang 1998, Gallou 2004) but this does not meet PS4 thresholds and is outweighed by population frequency data.6 ClinVar expert panel (ClinGen VHL VCEP) classifies this variant as Benign (VCV000161402).7 REVEL score of 0.559 does not meet the VHL VCEP PP3 threshold of ≥0.664. BayesDel score of -0.059 is consistent with a benign prediction.8 The variant alters codon 52, which is upstream of the second VHL initiation codon (Met54); only pVHL30 is affected while pVHL19 remains intact. This N-terminal region is outside recognized VHL critical functional domains.9
