Diagnosis of cystic fibrosis in a patient of Egyptian background.

Cystic fibrosis (CF) is the most common genetically inherited condition in European-derived populations. However, it is being increasingly recognised in other populations, including people of Asian, Black African and Caribbean descent. We present a case detailing the diagnosis of CF in a 12-year-old patient of Egyptian background who had been treated for difficult asthma. In doing so, we aim to highlight the importance of considering CF in all patients, regardless of ethnicity. 2016 BMJ Publishing Group Ltd.
