Gene and protein notation

Last revised by Dr Daniel J Bell on 20 Oct 2021

Correct usage of gene and protein notation has been laid down by the HUGO Gene Nomenclature Committee (HGNC) and on Radiopaedia we have decided to reflect this official guidance.

In concordance with this standard scientific practice, gene symbols are italicized on Radiopaedia, but when the full name of a gene is used it is to be in standard font, i.e. not italicized. 

Conversely protein symbols are to remain in a standard font, as are also protein names.

e.g. AHDS is the symbol for the "Allan-Herndon-Dudley syndrome gene". AHDS is the symbol for the "Allan-Herndon-Dudley syndrome protein" as expressed by the AHDS gene.

NB: this is one of the few occasions in which using italics is encouraged on Radiopaedia. If in doubt do not use them.
