How to Write Gene Notation Correctly: BRCA1 and Beyond
Learn how to write gene notation properly, including when to italicize gene names and use regular font for proteins like BRCA1.
Video transcript
Gene notation is written using a combination of letters and numbers. For example, in humans, the gene notation 'BRCA1' refers to the first breast cancer susceptibility gene. In general, gene names are italicized when handwritten or typed (e.g., _BRCA1_), and symbols for proteins are written in regular font (e.g., BRCA1). Always consult specific guidelines for different organisms.
Questions and answers
What is gene notation?
Gene notation is a standardized way of naming genes using letters and numbers, often italicized for gene names and written in regular font for protein symbols.
Why are gene names italicized?
Gene names are italicized to distinguish them from the proteins they encode, which are written in standard font.
How is the BRCA1 gene notation written?
The BRCA1 gene is written as BRCA1 and italicized as _BRCA1_ when handwritten or typed to indicate its status as a gene.
