We also included three monoallelic variants in Table 3, (variant c.8999G>A in DNAH5 gene; variant c.27T>G, in LRCC6 gene; and variant c.8555C>G, in DNAH11 gene,) which were detected in our patients, and shown to be potentially pathogenic, but these patients were not included in the above-mentioned 9 PCD patients. Here, DNAH11 is linked to primary ciliary dyskinesia.
