From Guidelines to Practice: Pilot Implementation and Analytical Boundaries of a Focused ADPKD-Spectrum Gene Panel.
Plain language
Genetic testing can clarify ADPKD, but test kits must prove they read every gene region reliably. A 16-sample pilot of a 28-gene kit read almost everything well — except PKD1 exon 1 and duplicated stretches. Panels need this kind of validation before routine use.
Clinical note
Pilot analytical-validity study (Diagnostics; n=16, two configurations). 82.7% of intervals at mean depth ≥20×; PKD1 exon 1 undercovered, duplicated sequence not callable. A lab validation story — do not order clinically on this basis.

If I have genetic testing for kidney cysts, what can the test miss and how would an unclear result be explained to me?
