DNAH9 and Neonatal respiratory distress: Conversely, individuals with biallelic MNS1 (Ta-Shma et al., 2018), DNAH9 (Fassad et al., 2018), CFAP53 (Silva et al., 2016) or RSPH1 (Knowles et al., 2014) mutations have a lower prevalence of neonatal respiratory distress and a later and milder onset of respiratory symptoms.
