It is not too late to insert <code> tags into your original post. You are able to update it any time.
As I understand you just want to output unique names of genes instead of raw rows. Than try this
#!/usr/bin/perl -lan
# Usage: thisscript.pl genes.txt
if ( $seen{ join ' ', sort @F }++ ) {
$uniq{$F[0]}++;
$uniq{$F[1]}++;
}
END {
print for keys %uniq;
}
And this:
Linux version:
perl -lane '@u{@F}=() if $s{join "", sort @F}++ }{ print for keys %u'
+genes.txt
Windows version:
perl -lane "@u{@F}=() if $s{join '', sort @F}++ }{ print for keys %u"
+genes.txt
Where genes.txt is a file containing gene rows
Feel free to ask if you need explanations on the algorithm and it's implementation.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
