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.

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

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

ZP1 is one of the four glycoproteins composing the human zona pellucida. ZP1-associated female infertility due to oocyte maturation defect has only been reported to date in 4 infertile sisters of a Han Chinese family (Huang et al. 2014). It is characterized by abnormal eggs that lack a zona pellucida. Affected individuals had normal menstrual cycles and sex hormone levels with no obstruction in the fallopian tubes or abnormalities of the uterus or adnexa.

Genetics

ZP1-associated female infertility is an autosomal recessive disorder (Huang et al. 2014). The ZP1 gene has 12 coding exons that encode one of the four glycoproteins composing human zona pellucida. The only genetic defect documented in ZP1 to date is a frameshifting small deletion found in the index Chinese family (Huang et al. 2014).

Clinical Sensitivity - Sequencing with CNV PGxome

Detection rate of pathogenic variants in the ZP1 gene in a large cohort of female patients with primary infertility is unknown in the literature because to date only a single family has been reported (Huang et al. 2014).

Testing Strategy

This test provides full coverage of all coding exons of the ZP1 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

Candidates for this test are female patients with primary infertility due to oocyte maturation defect. Testing is also indicated for family members of patients who have known ZP1 mutations. This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in ZP1.
