How does a low quantitative score on GRE general exam affect admissions to mathematics graduate programs?

I am applying to math grad school this fall (usually top 20-25).

I just took my GRE test and found out that my Quantitative score for General GRE is 156. I am not sure about the percentile yet.

Thus, if I want to present strong applications to math grad schools like UT Austin, UCLA, Columbia, Ohio State is the quantitative score enough?

The rest of my application is decent with about (3.7 gpa), research and publication. However I scored in the lower end of 600 for math gre. As you can tell I have high anxiety before such tests but I would like to avoid bringing up this point in my application as I am sure that the admission committee sees reason like this on its applications a lot.
