Yes, I see now... it is the awk -F'\t' '!seen[$4]++' that is removing the 4th line.

Code:
chr12:12006495-chr15:88483984 Fusion Gain-of-Function ETV6NTRK3-E4N15 1868
chr15:88483984-chr12:12006495 Fusion Gain-of-Function ETV6NTRK3-E4N15 1868
chr12:12022903-chr15:88483984 Fusion Gain-of-Function ETV6NTRK3-E5N15 414833
chr15:88483984-chr12:12022903 Fusion Gain-of-Function ETV6NTRK3-E5N15 414833

Since the lines in bold have the same $4 value only one of the lines needs to be printed.
The lines in italics have the same. This will only apply to those lines where SVTYPE=Fusion.

would adding the code in purple only remove the duplicates in the lines where SVTYPE=Fusion? Thank you very much Smilie.
Code:
   };
                        match($0,/oncomineGeneClass.*,/);
                        print "Locus\tType\tFunction\tGene\tReads"
                        print $1":"$2 "-" VAL OFS svtype OFS substr($0,RSTART+20,RLENGTH-22) OFS $3 OFS read_count;
                                   '{ if (a[$4]++ == 0) print $0; }' "$@"
            next
                    }
    1

desired output
Code:
chr12:12006495-chr15:88483984 Fusion Gain-of-Function ETV6NTRK3-E4N15 1868
chr12:12022903-chr15:88483984 Fusion Gain-of-Function ETV6NTRK3-E5N15 414833
chr17 entire line.... (this line does not have the keyword in it so is printed in the output)
chr10 entire line...   (this line does not have the keyword in it so is printed in the output

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
