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. If the Sanger option is selected, CNV detection may be ordered through Test #600.

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

Turnaround Time

18 days on average for standard orders or 13 days on average for STAT orders.

Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics

Clinical Features

Premature Ovarian Failure (POF), also known as premature ovarian insufficiency, is a genetically and phenotypically heterogeneous disorder characterized by primary amenorrhea or loss of menstrual function before the age of 40. Patients with POF often have elevated levels of follicle-stimulating hormone (FSH) and decreased levels of estrogen (Nelson. 2009. PubMed ID: 19196677). POF, in the most severe form, is a result of ovarian dysgenesis in which pubertal development is also severely affected. Approximately 50% of patients have varying and unpredictable ovarian function, and 5 to 10% of patients with POF may conceive without treatment (Nelson. 2009. PubMed ID: 19196677). There are several causes of premature ovarian failure, including chromosomal abnormalities, pathogenic sequence variants, autoimmune disorder, and environmental factors. POF can be isolated or part of a genetic syndrome (Kovanci and Schutt. 2015. PubMed ID: 25681846).

Genetics

Approximately 10-30% of POF cases have familial inheritance (Vegetti et al. 1998. PubMed ID: 9740426; van Kasteren et al. 1999. PubMed ID: 10527968). The inheritance can be autosomal recessive, dominant or X-linked. To date, defects in at least 15 genes, including FIGLA, have been reported to cause POF (Layman. 2013. PubMed ID: 23499866). FIGLA is a germ cell-specific basic helix-loop-helix (bHLH) transcription factor that regulates expression of oocyte-specific genes. It is critical in oocyte differentiation and required for normal folliculogenesis (Huntriss et al. 2002. PubMed ID: 12468641). Studies of FIGLA have demonstrated that pathogenic variants disrupted FIGLA binding to its heterodimer bHLH transcription factor TCF3 and potentially the formation of primordial follicles (Zhao et al. 2008. PubMed ID: 18499083; Bouilly et al. 2016. PubMed ID: 27603904). Heterozygous pathogenic variants, including missense variants and small deletions (one inframe and one frame-shift), in FIGLA have been reported to cause POF (Zhao et al. 2008. PubMed ID: 18499083; Bouilly et al. 2016. PubMed ID: 27603904).

Clinical Sensitivity - Sequencing with CNV PGxome

To date, only a few pathogenic variants in FIGLA have been documented. In a cohort of 100 Chinese patients with Premature Ovarian Failure, three pathogenic variants in FIGLA were identified (Zhao et al. 2008. PubMed ID: 18499083).

No large deletions or duplications involving FIGLA have been reported (Human Gene Mutation Database).

Testing Strategy

This test provides full coverage of all coding exons of the FIGLA 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. PGnome panels typically provide slightly increased coverage over the PGxome equivalent. PGnome sequencing panels have the added benefit of additional analysis and reporting of deep intronic regions (where applicable).

Dependent on the sequencing backbone selected for this testing, discounted reflex testing to any other similar backbone-based test is available (i.e., PGxome panel to whole PGxome; PGnome panel to whole PGnome).

Indications for Test

This test is for patients with premature ovarian failure. Testing is also indicated for family members of patients who have known FIGLA pathogenic variants.
