Overview
Although laryngomalacia is not associated with a specific gene, there is evidence that some cases may be inherited.[1][2] Relaxation or a lack of muscle tone in the upper airway may be a factor. It is often worse when the infant is on his or her back, because the floppy tissues can fall over the airway opening more easily in this position.[3]
