Pricing Comments

Testing run on PG-select capture probes includes CNV analysis for the gene(s) on the panel but does not permit the optional add on of exome-wide CNV analysis. Any of the NGS platforms allow reflex to other clinically relevant genes, up to whole exome or whole genome sequencing depending upon the base platform selected for the initial test.

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

This test is also offered via a custom panel (click here) on our exome or genome backbone which permits the optional add on of exome-wide CNV or genome-wide SV analysis.

Turnaround Time

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

Multiple endocrine neoplasia type 1 (MEN1; OMIM 131100) is an autosomal dominant disorder distinguished by tumors of the parathyroid glands, pancreatic islet cells, and anterior pituitary gland (reviewed by Pannett and Thakker Endocrine-Related Cancer 6:449-473, 1999). Some patients with MEN1 may also develop adrenal cortical tumors, carcinoid tumors, facial angiofibromas, collagenomas, or lipomas. Neoplasia of endocrine glands typically leads to excessive hormone production. As a result, the clinical manifestations of MEN1 are clearly related to the sites of the tumors. For example, ~95% of patients exhibit hypercalcemia, nephrolithiasis, or osteitis fibrosa cystica due to parathyroid tumors; ~40% have recurrent peptic ulcers, hypoglycemia, or hyperglucagonaemia due to pancreatic tumors; and ~30% have hyperprolactinaemia, hypercorticism (i.e. Cushing’s syndrome), or acromegaly due to anterior pituitary tumors.


Heterozygous germline variants in the menin gene (MEN1) predispose individuals to multiple endocrine neoplasia type 1 (MEN1). For mutant carriers, the penetrance of MEN1 is greater than 75% by the age of 25, and approaches 100% by the age of 60 (Pannett and Thakker. Endocr Relat Cancer 6(4): 449-73,1999). To date, at least 565 distinct causative variants have been found scattered throughout the MEN1 gene (Lemos and Thakker Hum Mut 29:22-32, 2008). Greater than 80% of these variants are inactivating (i.e. nonsense, frameshifts, splice-site), consistent with the role of MEN1 as a tumor suppressor gene (Larsson et al. Nature 332:85-87, 1988). Although the precise molecular function of the Menin protein is still not known, data from protein interaction studies suggest it is involved in many vital processes, including transcriptional regulation, DNA replication, and DNA repair (reviewed in Lemos and Thakker, 2008). In addition to familial cases of MEN1, heterozygous variants have also been found in patients with apparently sporadic cases of MEN1, as well as in patients diagnosed with familial isolated hyperparathyroidism (FIHP; OMIM 145000) (Warner et al. J Med Genet 41:155-160, 2004). Interestingly, ~40% of the causative variants found in FIHP cases are missense, compared to only ~20% for MEN1 (Lemos and Thakker, 2008). These observations suggest a likely association between weak missense variants and the mild clinical FIHP variant.

Clinical Sensitivity - Sequencing with CNV PG-Select

This test is predicted to detect a causative variant in ~50-95% of patients with autosomal dominant MEN1, ~70% of patients with sporadic or isolated MEN1, or ~20% of patients with FIHP (Agarwal et al. Hum Mol Genet 6:1169-1175, 1997; Teh et al. J Clin Endo Metab 83:2621-2626, 1998; Warner et al. J Med Genet 41(3): 155-60, 2004). Gross deletions of the MEN1 gene have been detected in up to 4% of patients (Falchetti et al. GeneReviews. 2010).

Testing Strategy

This test provides full coverage of all coding exons of the MEN1 gene, plus ~10 bases of flanking noncoding DNA. We define full coverage as >20X NGS reads or Sanger sequencing.

Indications for Test

Candidates for this test are patients diagnosed with multiple endocrine neoplasia type 1 (MEN1) or familial isolated hyperparathyroidism (FIHP). This test is specifically designed for heritable germline variants and is not appropriate for the detection of somatic variants in tumor tissue.
