Associated disorders

The OTX2 gene is associated with autosomal dominant microphthalmia, anophthalmia, coloboma (MAC) spectrum (MedGen UID: 468558). Additionally, the OTX2 gene has preliminary evidence supporting a correlation with autosomal dominant pituitary hormone deficiency (MedGen UID: 462790; PMID: 18728160) and autosomal dominant Leber congenital amaurosis (LCA) (PMID: 23847139, 15846561).

The OTX2 gene encodes the orthodenticle homeobox 2 protein. This is a homeodomain-containing transcription factor that is involved in brain, craniofacial, and sensory organ development.

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, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

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.
