L Guillot, R Epaud, G Thouvenin, L Jonard, A Mohsni, R Couderc, F Counil, J de Blic, R A Taam, M Le Bourgeois, P Reix, F Flamein, A Clement, D Feldmann. New surfactant protein C gene mutations associated with diffuse lung disease (J Med Genet 2009;46:490–4). There is an error in the genetic family tree of the L194P mutation. The authors would like to point out that it is the father who harbours and transmits the mutation to his child (arrow) and not the mother as published. The corrected figure is published below.
