- LoF loss of function
- aOne tumour lost a germline but gained a homozygous somatic mutation
- bComposite heterozygous mutations are considered as bi-allelic LoF
- cThe patient with a compound heterozygous LoF had two somatic frameshift mutations
- dOf the five patients with compound heterozygous LoF, four had both germline and somatic mutations and one had two somatic mutations
