The current HGVS version number is shown in the top right corner of this web site (“Version xx.xx”). Note the version does not change when a typing error is corrected, an example added, an explanation clarified or a question answered. Outside the core HGVS recommendations, covered by the version number, the recommendations have “named extensions”, i.e optional extensions for a specific use. Supporting named extensions is optional. A proper reference to the version of the HGVS nomenclature should mention the version number and the named extensions supported.

The current version is HGVS nomenclature v20.05.

NOTE: since proposals SVD-WG007 and SVD-WG008 have been accepted a new version of the HGVS nomenclature was released May 1, 2020.
