Clinical validity: Help
Based on published literature, aHUS sequencing has a clinical sensitivity of 50-70% and the clinical sensitivity of C3G is up to 40%. In one study, cblC deficiency showed a clinical sensitivity of 96%. Pathogenic variants for inherited TTP and Denys-Drash syndrome are only reported within single genes, but the clinical … View more

Analytical Validity: Help
The analytic specificity and sensitivity of the NGS panel are greater than 99%.
Assay limitations: Help
This test targets the exons of the selected 20 genes, plus 5 bp of intronic DNA flanking the exon-intron boundary. In addition, non-coding regions with known pathogenic variants, SNPs detecting risk haplotypes of CFH-H3 and CD46/MCP, a TSEN2 splice site variant causing a novel syndrome accompanied by aHUS, and two … View more
