The prognosis of patients ranges from excellent to extremely poor. [mdpi.com]
In the literature, the prognosis is generally considered to be good. However, in spinal or thoracic involvement, life-threatening complications can occur [ 10 ]. Management of Gorham-Stout syndrome is also a subject of controversy. [ped-rheum.biomedcentral.com]

Pathophysiology
Pathophysiologic mechanisms for SIDS may include respiratory dysfunction, cardiac dysrhythmias, cardiorespiratory instability, and inborn errors of metabolism, but definitive pathogenic mechanisms precipitating an infant sudden death remain elusive. [genecards.org]
Studies of such rare diseases could lead to a better understanding of the pathophysiology of ABCC9 -related syndromes. Appropriate genetic counseling and prenatal diagnosis for these patients and their families must also be stressed. [karger.com]
The disease pathophysiology commences with intramedullary and subcortical radiolucent foci resembling patchy osteoporosis. It makes slow, irregular, local progress with a concentric shrinkage of the shafts of the bones. [ped-rheum.biomedcentral.com]
Prevention
Tea tree oil : Tea tree oil is purported to have antiseptic properties, and has been used traditionally to prevent and treat infections. [livingnaturally.com]
Other interventions include arrhythmia management using device therapy and sudden death prevention. Patients who are refractory to medical therapy might benefit from mechanical circulatory support and heart transplantation. [centogene.com]
At least two mutations in the ABCC9 gene have been identified in people with dilated cardiomyopathy, a form of heart disease that enlarges and weakens the cardiac muscle, preventing the heart from pumping blood efficiently. [ghr.nlm.nih.gov]
