This case series reported nine molecularly confirmed Chinese CS patients from nine unrelated families in Hong Kong. Clinical phenotype and facial features of these nine Chinese CS patients together with four previously reported Chinese patients were reviewed. Typical presentations like coloboma and choanal atresia were not universally present. The prevalence of choanal atresia in these Chinese CS patients was found to be significantly lower than that in previous cohorts of other ethnic groups. This report highlighted the existence of phenotypic variation of CS among different ethnicities and suggested that a high index of suspicion is necessary for diagnosis of CS in Chinese patients.<\/jats:p>","DOI":"10.1002\/ajmg.a.61398","type":"journal-article","created":{"date-parts":[[2019,11,15]],"date-time":"2019-11-15T09:26:10Z","timestamp":1573809970000},"page":"15-19","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["CHARGE syndrome in nine patients from China"],"prefix":"10.1002","volume":"182","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9923-7424","authenticated-orcid":false,"given":"Shirley S.
