Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PS1_Very_Strong PM1 PM2 PM5 PP3_Strong PP5_Moderate

The NM_000551.4(VHL):​c.238A>C​(p.Ser80Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S80N) has been classified as Likely pathogenic.

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]

ACMG classification

Our verdict: Pathogenic. The variant received 20 ACMG points.

• PS1: Transcript NM_000551.4 (VHL) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.
• PM1: In a hotspot region, there are 33 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 4 benign, 29 uncertain in NM_000551.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr3-10142086-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1070179.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.963
• PP5: Variant 3-10142085-A-C is Pathogenic according to our data. Variant chr3-10142085-A-C is described in ClinVar as Pathogenic. ClinVar VariationId is 496052.Status of the report is criteria_provided_single_submitter, 1 stars.

Variant summary: The c.238A>C variant affects a conserved nucleotide, resulting in amino acid change from Ser to Arg. 4/4 in-silico tools predict damaging outcome for this variant. This variant has been reported in mutlitple VHL patients, including 10 affected members in one family. The variant is not found in 95076 control chromosomes. In addition, one reputable database classified this variant as "mutation". Amino acid changes at Ser80 (Ser80Gly, Ser80Ile, Ser80Asn) have been classified as pathogenic/likely pathogenic. Taken together, this variant was classified as pathogenic. -
