loop through lines and save into separate files

I have two files:
file-gene_families.txt that contains 30,000 rows of 30 columns. Column 1 is the ID column and contains the
Col1                  Col2  Col3 ...
One gene-encoded CBPs ABC  111 ...
One gene-encoded CBPs ABC  222 ...
One gene-encoded CBPs ABC  212 ...
Two gene encoded CBPs EFC   223 ...
Two gene encoded CBPs EFC   133 ...
Two gene encoded CBPs EFC   103 ...
Two gene encoded CBPs EFC   323 ...
Three gene(encoded) CBPs CGC  20 ...
Four gene/encoded (CBPs) GGH NULL ...
Four gene/encoded (CBPs) GGH 0 ...
Four gene/encoded (CBPs) GGH 1 ... 
Four gene/encoded (CBPs) GGH 2 ...
Four gene/encoded (CBPs) GGH 3 ...
Four gene/encoded (CBPs) GGH 56 ...

One gene-encoded CBPs
Two gene encoded CBPs
Three gene(encoded) CBPs
Four gene/encoded (CBPs)

I want separate file-gene_families.txt based on the file-group.list using the each line of file-group.list as the file names of the output, substitute these brackets space and slash with hyphen "-".
Two-gene-encoded CBPs.tmp

for example in One-gene-encoded-CBPs.tmp
One gene-encoded CBPs ABC  111 ...
One gene-encoded CBPs ABC  222 ...
One gene-encoded CBPs ABC  212 ...

Could not get my script working. Can someone help me out?
for line in $(cat At-GeneFamily-Unique-group.list)
name=$(sed 's/\ |\//-/g' $line)
grep $line gene_families.txt >> $name.tmp

Thanks a lot!

Use ksh to run the script ..
while read i
        name=$(echo $i | sed 's,(, ,g;s,),,g;s,/, ,g;s, ,-,g')
        grep "$i" file-gene_families.txt > ${name}.tmp

nawk '{print $0 >> $1}' inputfile

Thanks to you both! It works like a charm!
Raj, could you explain the script a little more detail? So simple and worked except some error, e.g. for those the first columns contains "/" did not go through.
$0 for the whole row,
$1 for the first column

What's the trick of the ">>" ? I am trying to combine the "sed" part to get rid of those special characters for the output file name.
Thanks a lot again!

Are columns TAB separated?
Based on your sample file, you have embedded space in what you call a 'first column' in the file-gene_families.txt

Yes, they are TAB separated.
That's why I want the embedded space replaced with hyphen in the output files. Not fully understand Raj's script, Jayan's works good though.
Thanks. YF

not tested...
nawk 'FNR==NR{f2[$0];next} $1 in f2 {a=$1;gsub("[ /()] ","-",a);out=(a ".txt"); print >> out;close(out)}' FS='\t' file-group.list file-gene_families.txt
