Given your data strictly follow the pattern above, you could select sets by numbers:
Code:
awk -F"[_.>\t]+" 'FNR>1 {N=(set-1)*5; X=$(N+4)+0; sub(X, "", $(N+4)); print $(N+2)+0, X, X, $(N+4), $(N+5)}' OFS="\t" set=5 /tmp/GJB-1_position.txt

Code:
for i in 1 2 3 4 5; do awk -F"[_.>\t]+" 'FNR>1 {N=(set-1)*5; X=$(N+4)+0; sub(X, "", $(N+4)); print $(N+2)+0, X, X, $(N+4), $(N+5)}' OFS="\t" set=$i /tmp/GJB-1_position.txt~; done
4004    79    79    G    A

4004    79    79    G    A
