Test Overview

Test Methodology

The coding exons and associated, flanking splice sites of the PTPN11 gene are amplified using specific primers, and bidirectionally sequenced using a fluorescent method.

Test Usage

To detect the presence of PTPN11 mutations in patients with a diagnosis of Noonan syndrome, LEOPARD syndrome, and other syndromes associated with PTPN11 mutations, particularly if SOS1 (with or without KRAS) mutation analysis was previously performed, and for carrier testing in families with a known PTPN11 mutation. All coding exons and associated flanking splice sites of the PTPN11 gene will be sequenced.

Reference Range

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements
