Pricing Comments

Our favored testing approach is exome based NextGen sequencing with CNV analysis. This will allow cost effective reflexing to PGxome or other exome based tests. However, if full gene Sanger sequencing is desired for STAT turnaround time, insurance, or other reasons, please see link below for Test Code, pricing, and turnaround time information.

An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.

For Reflex to PGxome pricing click here.

The Sanger Sequencing method for this test is NY State approved.

Turnaround Time

18 days on average for standard orders or 14 days on average for STAT orders.

Once a specimen has started the testing process in our lab, the most accurate prediction of TAT will be displayed in the myPrevent portal as an Estimated Report Date (ERD) range. We calculate the ERD for each specimen as testing progresses; therefore the ERD range may differ from our published average TAT. View more about turnaround times here.

Clinical Features and Genetics

Clinical Features

FBXO7-related Parkinson disease (Parkinson disease 15) is an important genetic cause for early onset Parkinson disease. The symptoms include progressive parkinsonism, pyramidal and extrapyramidal signs, lower limb spasticity, bradykinesia, rigidity, tremor, monotone speech, and postural instability. The onset of this disorder is from adolescence or young adulthood with slow progression. Patients have varying degrees of response to the pharmacologic replacement of dopamine, levodopa (Di Fonzo et al. 2009. PubMed ID: 19038853; Lai et al. 2012. PubMed ID: 23196729; Zhao et al. 2011. PubMed ID: 21347293).


FBXO7-related Parkinson disease (Parkinson disease 15) is inherited in autosomal recessive manner. The disease is caused by pathogenic variants in the FBXO7 gene which encodes F-box only protein 7. This protein is a subunit of the SCF (SKP1/cullin-1/F-box protein) E3 ubiquitin ligase complex. Animal model studies demonstrated that FBXO7 is a proteasome-associated protein involved in proteasome assembly. Loss of function leads to reduced proteasome activity and causes early-onset motor deficits (Vingill et al. 2016. PubMed ID: 27497298).

Pathogenic variants including nonsense, missense and splicing variants in FBXO7 gene have been published. No large deletions/duplications in the FBXO7 locus have been reported to date (Human Gene Mutation Database).

Clinical Sensitivity - Sequencing with CNV PGxome

Overall, FBXO7 causative variants are rare in patients with Parkinson disease (Gómez-Garre et al. 2014. PubMed ID: 24112787).

Testing Strategy

This test provides full coverage of all coding exons of the FBXO7 gene plus 10 bases of flanking noncoding DNA in all available transcripts along with other non-coding regions in which pathogenic variants have been identified at PreventionGenetics or reported elsewhere. We define full coverage as >20X NGS reads or Sanger sequencing.

Since this test is performed using exome capture probes, a reflex to any of our exome based tests is available (PGxome, PGxome Custom Panels).

Indications for Test

The test is recommended for patients suspected to have FBXO7-related Parkinson disease. This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in FBXO7.
