Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000036538	SCV000060193	likely benign	not specified	2010-10-05	criteria provided, single submitter	clinical testing	This variant has been reported in the literature in two individuals with tumors consistent with VHL syndrome. It was reported in the tumor of one individual wit h a central nervous system hemangioblastoma and in the blood of a second individ ual with a pheochromocytoma (Cybulski 2004, Meyer-Rochow 2009). However, this va riant is not expected to have clinical significance because it does not alter an amino acid residue and is not located near a splice junction. However, on rare occasions, nucleotide changes that do not result in amino acid changes can be as sociated with disease.

GeneDx	RCV000036538	SCV000211835	benign	not specified	2014-09-29	criteria provided, single submitter	clinical testing	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Ambry Genetics	RCV000161100	SCV000213981	likely benign	Hereditary cancer-predisposing syndrome	2014-11-12	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000036538	SCV000918338	benign	not specified	2018-05-07	criteria provided, single submitter	clinical testing	Variant summary: VHL c.150C>G alters a non-conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant was observed with an allele frequency of 0.0005 in 211956 control chromosomes (gnomAD). The observed variant frequency is approximately 24-folds higher than the estimated maximal expected allele frequency for a pathogenic variant in VHL causing Von Hippel-Lindau Syndrome phenotype (2.1e-05), strongly suggesting that the variant is benign. The variant, c.150C>G, has been reported in the literature in individuals affected with Von Hippel-Lindau Syndrome (Meyer-Rochow_2008). These report(s) do not provide unequivocal conclusions about association of the variant with Von Hippel-Lindau Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Clinvar submission from a clinical diagnostic laboratory (evaluation after 2014) cites the variant as "benign." Based on the evidence outlined above, the variant was classified as benign.

Illumina Laboratory Services, Illumina	RCV001150099	SCV001311111	benign	Von Hippel-Lindau syndrome	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.
