The PITX2 gene is associated with autosomal dominant Axenfeld-Rieger syndrome (ARS) (MedGen UID: 811487) and autosomal dominant iridogoniodysgenesis (MedGen UID: 330750). Additionally, the PITX2 gene has limited evidence supporting a correlation with Peters anomaly (PMID: 10051017) and ring dermoid of cornea (PMID: 15591271).
The PITX2 gene encodes the paired like homeodomain 3 transcription factor protein that belongs to the RIEG/PITX homeobox family. This protein is thought to be important in the development of the eye, tooth and abdominal organs and in myogenesis. It may also be important in the determination of left-right asymmetry during development.
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.
