Nature Genet. 32, 97–105 (2002).

On page 97, paragraph 2, line 13, 'IL-29' should be 'IL-27'.

On page 98, line 11, 'seemed to be' should be 'was', as this has been demonstrated to be the case.

On page 98, Fig. 1, a mistake in the color coding occurred, and the affected genes that appear in purple should be colored red.

On page 100, line 1, 'IL12Rb1' should read 'IL12Rβ1'.
