We have reviewed our policy on the use of HGVS nomenclature for the naming of DNA sequence variants. The most significant changes made are as follows:
- EMQN expects laboratories to report their results using HGVS nomenclature (http://varnomen.hgvs.org/) recommending that laboratories implement the latest version (currently v. 19.01).
- In the technical EQA scheme for Sanger Sequencing it is no longer required that variants are reported using full HGVS genotype nomenclature e.g. it is acceptable to state: “…is heterozygous for the CFTR c.1521_1523delCTT p.(Phe508del) variant”, rather than stating the full genotype c.[1521_1523delCTT];[=] p.[(Phe508del)];[(=)]. Additionally it is acceptable to describe an allele with no clinically relevant variants in words rather than using HGVS e.g. no pathogenic variant identified (homozygous).
