Additionally, quantitative high speed video analysis (HSVA) analysis of the beating pattern from single cilia revealed distinctive ‘fingerprints’ that can distinguish between healthy controls and samples mutated for PCD genes, such as HYDIN and DNAH11. Hence, the phenotypic parameters demonstrated with this technique not only allow for discrimination between healthy and PCD samples but also between PCD genotypes [62]. Here, DNAH11 is linked to primary ciliary dyskinesia.
