Central Hypoventilation Syndrome Panel
- Central hypoventilation syndrome is a disorder that affects breathing that can result in a shortage of oxygen and buildup of carbon dioxide in the blood. Generally, individuals affected will take shallow breaths and hypoventilate. In a healthy individual, the nervous system controls involuntary body processes that would react to such an imbalance but this reaction is impaired in individuals with CCHS (1). Some symptoms include abnormal pupils, feeding difficulty, absent or impaired bowel function, but most importantly poor breathing or complete lack of spontaneous breathing (2, 3). A milder later-onset presentation of the syndrome can be seen in toddlers, children and adults. All individuals with CCHS may have a mutation in the PHOX2B gene which plays an important role in the prenatal development of the autonomic nervous system (2). The condition affects females and males in equal numbers, though the true prevalence is unknown there are reportedly around 1,000 cases worldwide. The condition itself can easily go unrecognized or misdiagnosed, thus it is difficult to estimate the true frequency of CCHS in the general population (2).
