OK.

For your code, put the && within the single if's parentheses:
Code:
awk ' {if (($4 in arr) && (arr[$4]==$1)) { print arr[$4],$4} else {arr[$4]=$1} }' file

But this won't print your desired result. Try
Code:
awk '($4 in LN) && ($1 != CHR[$4]) {print LN[$4]; print} {LN[$4] = $0; CHR[$4] = $1}' file
2       seq-rs587779124 0       47702411        0       D
17       seq-rs5827779124 0       47702411        0       D
