Variant summary

Our verdict is Pathogenic. Variant got 22 ACMG points: 22P and 0B. PS1 PM1 PM2 PM5 PP3_Strong PP5_Very_Strong

The NM_000551.4(VHL):​c.240T>A​(p.Ser80Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. 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 Likely pathogenic (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Pathogenicin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S80G) 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

Verdict is Pathogenic. Variant got 22 ACMG points.

• PS1: Transcript NM_000551.4 (VHL) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar as 496052
• PM1: In a hotspot region, there are 12 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 13 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 chr3-10142085-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 186220.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.968
• PP5: Variant 3-10142087-T-A is Pathogenic according to our data. Variant chr3-10142087-T-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 3148494.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

This variant is considered likely pathogenic. This variant has been reported in multiple individuals with clinical features of gene-specific disease [PMID: 19755989, 12624160, 33720516, 12202531, 20978319, 8956040, 29748190]. This variant is expected to disrupt protein structure [Myriad internal data]. -

The p.S80R variant (also known as c.240T>A), located in coding exon 1 of the VHL gene, results from a T to A substitution at nucleotide position 240. The serine at codon 80 is replaced by arginine, an amino acid with dissimilar properties. Other alterations at the same codon, including p.S80R (c.240T>G) and p.S80G (c.238A>G), have been described in multiple individual with a personal and/or family history that is consistent with VHL-related disease (Crossey PA et al. Hum Mol Genet, 1994 Aug;3:1303-8; Woodward ER et al. Hum Mol Genet. 1997 Jul;6(7):1051-6; Assadi F & Brackbill EL. Am J Kidney Dis. 2003 Jan;41(1):E3; Erlic Z et al. Endocr Relat Cancer, 2010 Dec;17:875-83; Krauss T et al. Endocr Relat Cancer, 2018 Sep;25:783-793). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -
