Notes:

Sequencing of the PKD1 gene is challenging due to high homology with six known pseudogenes (exons 1-33).
Our NGS assay is specifically designed to provide superior mapping quality and uniform coverage across the coding region of PKD1, enabling robust detection of variants including indels. For mapping quality of >20, 99.7% of the targeted nucleotides have a mean coverage of 264 reads; even at a mapping quality of >40, mean coverage is 254x.
PKD1 variants are confirmed by long-range, nested PCR and capillary sequencing.

Clinical Utility:

Molecular confirmation of a clinical diagnosis;
Development of appropriate evaluation and management plan;
Evaluation of family members as possible donors for kidney/liver transplantation;
Testing of at-risk relatives for specific known variant(s) previously identified in an affected family member;
Prenatal diagnosis for known familial pathogenic variant(s) in at-risk pregnancies;
Genetic counseling, especially recurrence risk and prenatal diagnosis

Notes:

Sequencing of the PKD1 gene is challenging due to high homology with six known pseudogenes (exons 1-33).
Our NGS assay is specifically designed to provide superior mapping quality and uniform coverage across the coding region of PKD1, enabling robust detection of variants including indels. For mapping quality of >20, 99.7% of the targeted nucleotides have a mean coverage of 264 reads; even at a mapping quality of >40, mean coverage is 254x.
PKD1 variants are confirmed by long-range, nested PCR and capillary sequencing.
For Deletion/Duplication analysis, Multiplex Ligaton-Dependent Probe Amplification (MLPA) is performed.

Rare Disorders Variant Testing Program (VTP)

Laboratories classify genetic changes as variants of uncertain significance (VUS) if there is incomplete or conflicting information about the health consequences of the variant. In some cases, testing family members for the presence or absence of the VUS may contribute to a better understanding of the variant and may be one piece of evidence leading to eventual reclassification of a VUS as a pathogenic, likely pathogenic, benign, or likely benign variant. For such cases, GeneDx has established a Variant Testing Program (VTP).

How do I determine if a variant is eligible for the Rare Disorders VTP?

GeneDx considers requests for the Rare Disorders VTP for any individual found to have a VUS in a disease-causing gene through exome or genome sequencing at our laboratory. These studies will be performed at no additional charge for select and pre-approved family members who meet certain criteria and for whom appropriate clinical information is provided. Genetic testing for other variants or additional family members, including predictive testing, is not included in our VTP and can be ordered separately for charge. GeneDx will make the final determinations for VTP in its sole discretion.

Application process for the Rare Disorders VTP:

Please fax a detailed pedigree and any relevant clinical information/evaluations to the GeneDx Rare Disorders VTP genetic counselors at 301-519-2892, email zebras@genedx.com, or call 301-519-2100 and ask to speak with an Rare Disorders genetic counselor. Please be sure to indicate that you are submitting the information for VTP consideration, and include the name and/or GeneDx accession number of the proband.
Our team will review the case and will determine if there are informative family members appropriate for evaluation through the VTP. Cases are typically reviewed within a few days, but please allow up to 3 weeks after receipt of the application for a reply.
A member of our team will contact the ordering clinician after the case has been reviewed to let him/her know if the family has been accepted in the VTP. If we are extending an offer for family member variant testing at no additional charge, we will discuss logistics of sample submission at that time.

Reasons why a family might not be accepted into the Rare Disorders VTP:

The VUS is in a gene for which there is no currently described phenotype (i.e. candidate or novel gene).
There are no informative family members available for testing.
In certain circumstances, it may be more informative to perform more comprehensive diagnostic genetic testing in affected family member(s) instead of targeted testing of one or more unaffected relatives for a VUS.
Segregation studies involving genes with incomplete penetrance or variable age-of-onset are challenging, especially in unaffected individuals; therefore, VTP studies are less likely to be approved for such genes.
Segregation studies involving genes that may cause either an autosomal dominant or an autosomal recessive disorder are also more challenging than studies involving highly penetrant autosomal dominant genes; therefore, VTP studies are less likely to be approved for such genes.
Variant studies for the evaluation of a single VUS in a gene associated with an autosomal recessive disorder are rarely informative. Therefore, these requests are typically denied.

Revising the classification of variants of uncertain significance takes a great deal of data and information from multiple sources. Therefore, there is no guarantee that participation in the VTP will lead to an updated classification of a VUS based on information from a single family, although cumulative data collected from multiple families over time may lead to a more definitive classification for a variant.
