  1. Three (SNG190, SNG178, SNG057) have been validated by Sanger sequencing of patient plus parents. Of these 18 variants, 6 classified as ACMG pathogenic or likely pathogenic, the remainder are undefined. Full details of these variants are provided in Table S2. Details of a further 27 putative candidate diagnoses that remain under clinical review are provided in Table S2. Rank indicates rank in our pipeline; OMIM API? indicates whether the diagnosis was made by direct access to the OMIM API (1 = yes; 0 = No); Phenotypic Series indicates whether the diagnosed gene was identified via the phenotypic series in OMIM (1 = yes; 0 = No). N Het is the number of individuals in the cohort heterozygous for the variant; N Hom the number of homozygous individuals. One patient was listed as a possible compound heterozygote.
  2. AD autosomal dominant, AR autosomal recessive, IC isolated cases, P pathogenic, LP likely pathogenic, VUS variant of unknown significance (categorized as undefined in our pipeline), LoF number of loss-of-function variants seen in this gene in the cohort.
  3. aFull details of transcripts are provided in Table S2.
