Ian Berry (Leeds Genetics Laboratory)

Green List (high evidence)

Included all genes listed in clinical cases in Lynch et al 2015 PMID:28334938 and Ayrignac et al. 2015 PMID: 25527826. Included all genes with clear adult onset listed in Vanderver 2017 PMID:27159321 and Ahmed et al. 2017 PMID:24357685. A small number of genes from these resources were omitted, particularly those with limited or single case reports referenced in Ahmed et al, those with a metabolic basis (that could be determined by standard metabolic assays), and recessive diseases where the likelihood of encountering incidental carrier status is far more likely than finding a diagnosis e.g. Cockayne syndrome. Due to variable expressivity and potential later onset of phenotype in hypomorphic cases, peroxisomal biogenesis disorders OMIM phenotypic Series PS214100 and GeneReviews PMID:20301621 included.
