Son of Susie? (5)

I believe the answer is:

issue

'son' is the definition.
(I know that son can be written as issue)

'of susie?' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'susie' is an anagram of 'ISSUE'.

(Other definitions for issue that I've seen before include "Children; topic for debate" , "Important topic for offspring" , "Emerge" , "Susie (anag.)" , "Shares" .)

I've seen this clue in The Globe and Mail.
