CFTR and cystic fibrosis: El-Falaki et al showed similar results with majority of patients had symptoms in first year of life and diagnosis was made after second year of life.9 This delay is partly due to lack of rationalizing CF by health care provider as an important differential diagnosis and partly by non-availability of facilities assistingearly diagnosis.10 More than half of our cohort had parents with consanguineous marriages which is similar to Desgeorges M et al. from Lebanon who found 50% rate of consanguineous marriage in their CF population.11 More than 1800 mutations have been reported for CFTR gene.
