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.

3 weeks on average for standard orders or 2 weeks 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
Male infertility is a reproductive disorder affecting 10-20% of couples worldwide. Common causes of male infertility include little or no sperm in the semen (azoospermia and oligozoospermia), low sperm motility (asthenozoospermia) and abnormal sperm morphology (teratozoospermia) (Cooke and Saunders. 2002. PubMed ID: 12360237). Globozoospermia is a rarer form of teratozoospermia characterized by round-headed spermatozoa with acrosome malformation or without an acrosome. Globozoospermia accounts for less than 0.1% of male infertile patients (Dam et al. 2007. PubMed ID: 17008355). While intracytoplasmic sperm injection (ICSI) has been used to treat these patients, the pregnancy rate per transfer is low due to a reduced ability to activate the oocyte (Achard et al. 2007. PubMed ID: 17412686).
Genetics
PICK1-related globozoospermia is an autosomal recessive disorder (Liu et al. 2010. PubMed ID: 20562896). The PICK1 gene has 12 coding exons that encode a protein interacting with protein kinase C, alpha (PRKCA). Genetic defects of PICK1 to date have been only found in one Chinese family with globozoospermia type I, and involve a missense pathogenic variant p.Glu198Ala (Liu et al. 2010. PubMed ID: 20562896).
Clinical Sensitivity - Sequencing with CNV PGxome
A PICK1 pathogenic variant has been only identified in only one family with globozoospermia (Liu et al. 2010. PubMed ID: 20562896).
To date, no gross deletions or duplications involving PICK1 have been reported (Human Gene Mutation Database).
Testing Strategy
This test provides full coverage of all coding exons of the PICK1 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 patients with globozoospermia. Testing is also indicated for family members of patients who have known pathogenic variants in the PICK1 gene. This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in PICK1.

For Requisition Forms, visit our Forms page
If ordering a Duo or Trio test, the proband and all comparator samples are required to initiate testing. If we do not receive all required samples for the test ordered within 21 days, we will convert the order to the most effective testing strategy with the samples available. Prior authorization and/or billing in place may be impacted by a change in test code.
