Visceral heterotaxy-11 (HTX11) is characterized by a failure to generate normal left-right visceral asymmetry during embryogenesis, which can result in heterotaxy syndrome or situs inversus totalis. Affected individuals may experience mild chronic respiratory symptoms, but do not fulfill the criteria for primary ciliary dyskinesia (see 244400). Male infertility associated with reduced flagellar motility has been reported (Dougherty et al., 2020). For a discussion of genetic heterogeneity of visceral heterotaxy, see HTX1 (306955).
