Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PM1PM2PP3_StrongPP5_Very_Strong
The NM_000551.4(VHL):c.266T>C(p.Leu89Pro) 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 Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L89F) has been classified as Uncertain significance.

Von Hippel-Lindau syndrome Pathogenic:3

Variant summary: VHL c.266T>C (p.Leu89Pro) results in a non-conservative amino acid change located in the von Hippel-Lindau disease tumour suppressor, beta/alpha domain (IPR022772) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 225978 control chromosomes (gnomAD). c.266T>C has been reported in the literature in multiple individuals and families affected with Von Hippel-Lindau Syndrome (e.g. Crossey_1994, Glavac_1996, Chacon-Camacho_2010, Liu_2018). These data indicate that the variant is very likely to be associated with disease. Three ClinVar submitters (evaluation after 2014) cite the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
This variant is considered pathogenic. This variant has been reported in multiple individuals with clinical features of gene-specific disease [PMID: 8707293, 20447124, 17024664, 31620170]. This variant is expected to disrupt protein structure [Myriad internal data]. -
Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Pathogenic:1
This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 89 of the VHL protein (p.Leu89Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with von Hippel-Lindau syndrome (PMID: 7987306, 8707293, 11309459, 17024664, 20151405). It has also been observed to segregate with disease in related individuals. This variant is also known as 479T>C and Leu160Pro. ClinVar contains an entry for this variant (Variation ID: 182979). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt VHL protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
Hereditary cancer-predisposing syndrome Pathogenic:1
The p.L89P variant (also known as c.266T>C), located in coding exon 1 of the VHL gene, results from a T to C substitution at nucleotide position 266. The leucine at codon 89 is replaced by proline, an amino acid with similar properties. This variant has been reported in numerous VHL kindreds to date (Crossey PA et al. Hum. Mol. Genet. 1994 Aug;3:1303-8; Zbar B et al. Hum. Mutat. 1996;8:348-57; Glavac D et al. Hum. Genet. 1996 Sep;98:271-80; Webster AR et al. Arch. Ophthalmol. 1999 Mar;117:371-8; Klein B et al. Hum. Genet. 2001 May;108:376-84; Ong KR et al. Hum. Mutat. 2007 Feb;28:143-9; Rajasekaran R et al. Mamm. Genome. 2008 Sep;19:654-61; Nordstrom-O'Brien M et al. Hum. Mutat. 2010 May;31:521-37). This amino acid position is highly conserved through mammals but not in all 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. -
