The primary findings of the study are that (1) 12% of all pediatric subjects with TS21 included had a central apnea index (CAI)\u2009&gt;\u20092\/h; (2) the proportion of TS21 individuals with central breathing abnormalities progressively decreased with age being common in young individuals (\u22642 years of age) but rare after 10 years of age; (3) additional sleep breathing disturbances (e.g., OSA and\/or hypoxemia) are often present in children with TS21 and central apnea; and (4) the prevalence of central breathing abnormalities in TS21 is influenced by sex, being more likely to persist beyond early childhood (&gt;2 years of age) in females than in males.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Central breathing abnormalities are common in TS21 among young children (\u22642 years of age) and in females older than 2 years of age.
