Pathogenic NOTCH1 variants are associated with 30%-50% of clinical cases of Adams-Oliver syndrome and are a rare cause of aortic-valve disorder.

The NOTCH1 gene encodes a class I transmembrane protein that regulates cell fate decisions during development by functioning as a ligand-activated transcription factor. It plays an important role during embryogenesis, cell fate specification, maintenance of stem cells, proliferation and apoptosis (PMID: 23102684, PMID: 25132448).

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
