Paternally Inherited Inactivating Mutations of the GNAS1 Gene in Progressive Osseous Heteroplasia (Original Article, N Engl J Med 2002:346;99 - 106) . Line 2 of the legend for Figure 3 should have read, “mutated GNAS1 genomic DNA from patients” rather than “from control subjects.” Line 4 of the summary of the article in “This Week in the Journal” should have read, “mild heterotopic ossification” rather than “extensive heterotopic ossification.” We regret the errors.
