Focused Autosomal Dominant Polycystic Kidney Disease Gene Panel, Varies

Clinical Use

Use

This test provides a genetic evaluation for patients with a personal or family history suggestive of autosomal dominant polycystic kidney disease (ADPKD). It helps establish a diagnosis of ADPKD, which is characterized primarily by bilateral kidney cysts, liver cysts, and an increased risk for intracranial aneurysm. The test identifies pathogenic variants which may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for ADPKD.

Special Instructions

Not provided.

Limitations

Next-generation sequencing may not detect all types of genomic variants, and false-negative or false-positive results may occur. Certain sequences, such as those with homology, high guanine-cytosine content, and repetitive sequences, may not be evaluated effectively. Deletions up to 75 bp and insertions up to 47 bp are detected with high sensitivity, but larger delins may be less reliably detected. This test does not detect low levels of mosaicism or differentiate somatic from germline variants.
