extract rows from one file based on values from another file - LINUX

I am new to linux, and got this elementary question,,,

I would like to extract rows from a text file-A BASED on another text file-B containing the values of gene name (ABD, GHE)

so the output would be

chr gene start stop pval
    2   ABD  5667  5789 0.03
    5   GHE  4556  4784 0.34

file A

chr gene start stop pval
1   xic  455   467 0.005
2   ABD  5667  5789 0.03
5   GHE  4556  4784 0.34

file B

How about this?

head -n 1 A ; grep -f B A
chr gene start stop pval
2   ABD  5667  5789 0.03
5   GHE  4556  4784 0.34
