We investigated a family in which both parents were initially found carriers for a common pathogenic mutation in <em>NCF1<\/em>, one of the genes causing this disease. Genetic analysis of the fetus yielded conflicting results as to its affection status, but white blood cells acquired through cordocentesis reacted normally. Eventually the child was born and proved healthy. Further analysis showed that the discrepancy was caused by gene copy number variation at the <em>NCF1<\/em> locus. Our results have important implications regarding <em>NCF1<\/em> carrier screening.
