An estimated 2% of all PCD is caused by the presence of two pathogenic variants identified in DNAAF2.
Ciliary movement protects the lungs, sinuses and ear canals from recurrent infections by clearing mucus, dirt and bacteria out of the respiratory tract. Motile cilia consist of nine peripheral microtubule doublets encircling two central microtubules. Inner and outer dynein arms attached at regular intervals along the peripheral microtubules and radial spokes linking the peripheral and central microtubules act as molecular motors to generate planar movement. The DNAAF2 gene encodes a cytoplasmic dynein arm assembly factor. Mutations in this gene lead to dysfunctional motile cilia with both outer dynein arm (ODA) and inner dynein arm (IDA) structural defects (PMID: 25826585).
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.
