In this Letter, the ‘Data availability’ section in the Methods should state ‘WES and RNA-seq data are deposited in dbGaP (https://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?study_id=phs001451.v1.p1). All other data are available from the corresponding author upon reasonable request.’ instead of ‘All data are available from the corresponding author upon reasonable request’. In addition, the ‘Competing interests’ statement should include: ‘C.J.W. is subject to a conflict of interest management plan for the reported studies because of her competing financial interests in Neon Therapeutics. Under this plan, C.J.W. may not access identifiable human subjects’ data nor otherwise participate directly in the IRB-approved protocol reported herein. C.J.W.’s contributions to the overall program strategy and data analyses occurred on a de-identified basis.’ These errors have been corrected in the online versions of the Letter.
