The 25-year-old has been linked with moves to a number of clubs including QPR, Bolton Wanderers, Everton and Wolverhampton Wanderers.
"Manchester City officials have not given Nedum permission to meet QPR or any other clubs' officials with a view to holding face-to-face discussions regarding a loan deal or permanent move," Dr Anthonia Onuoha told Sky Sports News.
"The latest report of a move to QPR this weekend is, therefore, totally inaccurate.
"Nedum has two-and-a-half years left on his current Manchester City contract and will only make a move that is right both for his career and family circumstances. We have a number of clubs interested in him. He will weigh up his options before making any decision."
Onuoha, who spent last season on loan at Sunderland, has made one league appearance for City during this campaign.
