Nephrocalcinosis, Nephrolithiasis, and Renal Electrolyte Imbalance Gene Panel, Varies

Clinical Use

Use

This test provides a genetic evaluation for patients with a personal or family history suggestive of a hereditary form of nephrocalcinosis, nephrolithiasis, or renal electrolyte imbalance. It helps in establishing a diagnosis for a variety of hereditary conditions associated with renal salt wasting or abnormal salt retention, impaired acid-base, water, and calcium homeostasis, or kidney crystallization. Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for these hereditary conditions.

Special Instructions

Not provided.

Limitations

Next-generation sequencing may not detect all types of genomic variants. False-negative or false-positive results may occur. There may be regions of genes that cannot be effectively evaluated due to technical limitations, including regions of homology, high guanine-cytosine content, and repetitive sequences. Deletions-insertions of 40 or more base pairs may be less reliably detected than smaller delins. Del/Dup analysis targets single and multi-exon deletions/duplications, but some instances of single exon resolution cannot be achieved due to isolated reduction in sequence coverage or genomic complexity. This test does not detect low levels of mosaicism or differentiate between somatic and germline variants.
