We investigate the quantitative implications for deep inelastic neutrino scattering of a proposed additional V+A charm-changing current c$gamma$/sub mu/(1- $gamma$$sub 5$) d. Quark-parton-model spectrum-averaged predictions are compared with available $nu$N and nu-barNy distributions as obtained at Fermilab. Agreement is achieved with an effective charm threshold W)=4 GeV. A characteristic feature is an enhanced sea contribution that can account for the anomaly in dsigma/dy for nu-barN. Predictions for sum rules are significantly changed at high energy.
