Supplementary Table 2: List and results of 23 different known mutations/variants of 18 patients in 18 different NPHP-AC genes used for proof of principle of the MPR and DNA pooling strategy.Mutation numbering is based on cDNA position in reference sequences indicated in Table 1 with +1 corresponding to the A of the ATG translation initiation codon. (h), heterozygous; H, homozygous. Mutations not discovered with next-generation sequencing and CLC Genomics Workbench™ software analysis are indicated in bold.
