Interpreting In Silico scores in SDH Variant DBs
We provide REVEL (unfortunately, due to technical reasons in the column named "Mutation Taster"), AGVGD and SIFT scores. REVEL (rare exome variant ensemble learner) is an ensemble method for predicting the pathogenicity of missense variants on the basis of the individual tools MutPred, FATHMM, VEST, Poly-Phen, SIFT, PROVEAN, MutationAssessor, MutationTaster, LRT, GERP, SiPhy, phyloP, and phastCons. (N.M. Ioannidis et al. American Journal of Human Genetics 99, 877–885, October 6, 2016). Align-GVGD assesses biophysical characteristics of amino acids and protein multiple sequence alignments to predict impact, with a score somewhere between 0 and 250, the higher the scores the more deleterious the change. The GD score is provided and is often very similar to raw Grantham traditional scores. SIFT (Sorting Intolerant From Tolerant) predicts whether an amino acid substitution affects protein function based on sequence homology and the physical properties of amino acids. In general, SIFT provides the least informative of the three scores. In general, scores above 0.6 in REVEL and scores above 80 in AGVGD indicate potentially pathogenic variants. Known pathogenic variants present in SDH LOVD invariably show high scores.
A VUS in PPGL/HNPGL?
In the opinion of the curator the use of the term “VUS” is now excessive. In the case of rare diseases with variants in known causative genes, the emphasis should not be conservative (as in common conditions) but should assume causation and seek supportive evidence (conservation, protein region affected, in silico prediction tools, number of time reported in patients and in gnomAD). Only when no supporting evidence is found should one use the term “VUS”.
CITATION: if you benefit from the use of this database and publish findings, please cite; Bayley JP, Devilee P, Taschner PE (2005). BMC Med Genet. 6:39.
The variants included in the database were derived from the published literature or submitted directly and, where necessary, annotated to conform to current HGVS mutation nomenclature. When you notice any omissions or mistakes, please let us know (thank you).
Disclaimer: inclusion of sequence variants in the SDH mutation database does not imply that there is convincing evidence for pathogenicity. |
