Genes affected
VHL (HGNC:12687): (von Hippel-Lindau tumor suppressor) This gene encodes a component of a ubiquitination complex. The encoded protein is involved in the ubiquitination and degradation of hypoxia-inducible-factor (HIF), which is a transcription factor that plays a central role in the regulation of gene expression by oxygen. In addition to oxygen-related gene expression, this protein plays a role in many other cellular processes including cilia formation, cytokine signaling, regulation of senescence, and formation of the extracellular matrix. Variants of this gene are associated with von Hippel-Lindau syndrome, pheochromocytoma, erythrocytosis, renal cell carcinoma, and cerebellar hemangioblastoma. [provided by RefSeq, Jun 2022]

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change affects the initiator methionine of the VHL mRNA. The next in-frame methionine is located at codon 54. 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. This variant is not present in population databases (gnomAD no frequency). Disruption of the initiator codon has been observed in individual(s) with breast cancer and/or pilocytic astrocytoma (PMID: 30093976, 33840814). ClinVar contains an entry for this variant (Variation ID: 582995). 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). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.M1? variant (also known as c.3G>C), located in coding exon 1 of the VHL gene, results from a G to C substitution at nucleotide position 3. This alters the methionine residue at the initiation codon. Variations that modify the initiation codon (ATG) are expected to result in either loss of translation initiation or N-terminal truncation; however, an alternate initiation codon exists downstream of this alteration, and is reported to result in a biologically active isoform, known as VHL19 (Schoenfeld A et al. Proc. Natl. Acad. Sci. U.S.A. 1998 Jul; 95(15):8817-22; Iliopoulos O et al. Proc. Natl. Acad. Sci. U.S.A. 1998 Sep; 95(20):11661-6). This amino acid position is well conserved in available vertebrate species. Based on the available evidence, the clinical significance of this variant remains unclear.
