X marks the chromosome

Some days at work I’m in the lab all day. Some days I’m at the computer. Today was a computer day and my fingers were getting a little lazy. I was typing up a lot of documentation on a gene found on the X chromosome, and both the words “X” and “chromosome” were being typed a lot, and also the word “XIST,” which is the name of the gene. Suddenly, I realized that I had been typing this gem: “xhromosome.”

I rather like it. Could it be used as a way to abbreviate the term for “X chromosome?”
