  1. Sample IDs representing the discovery cohort are in bold and the remaining samples are from the validation cohort.
  2. Single-nucleotide variants were classified on the basis of DNA methylation data, clinical assessment and mutation databases. Each variant was classified by each of the mutation effect prediction algorithms independently.
  3. *Photos available, but did not meet inclusion criteria for clinical review.
  4. Both parents tested negative for the variant in NSD1. Also, non-paternity was ruled out in this de novo variant case.
