Delta F 508 molecular mutation in Indian children with cystic fibrosis
1Department of Paediatrics, All India Institute of Medical Sciences, New Delhi.
Insights
Cystic fibrosis (CF) is confirmed in Indian children, with the common delta F 508 mutation found in over half of affected chromosomes. Early screening for persistent respiratory or malabsorption issues is recommended.
Area of Science:
- Medical Genetics
- Pediatrics
- Pulmonology
Background:
- Cystic fibrosis (CF) is a genetic disorder typically affecting individuals of European descent.
- The prevalence and genetic basis of CF in the Indian population remain under-investigated.
Purpose of the Study:
- To investigate the presence of cystic fibrosis in Indian children.
- To determine the frequency of the delta F 508 mutation, the most common CF-causing mutation, in this cohort.
Main Methods:
- A preliminary screening of 13 Indian children diagnosed with cystic fibrosis was conducted.
- Genetic analysis focused on identifying the delta F 508 mutation.
Main Results:
- Six out of 13 patients (46%) were homozygous for the delta F 508 mutation.
- Two patients were compound heterozygotes for the delta F 508 mutation.
- Overall, the delta F 508 mutation was present on 14 out of 26 (53.8%) mutant chromosomes.
Conclusions:
- This study confirms that cystic fibrosis occurs in Indian children.
- The delta F 508 mutation is a significant cause of CF in this population.
- Screening for CF is recommended for Indian children presenting with persistent respiratory problems or malabsorption.
Abstract:
A preliminary report of 13 Indian children with cystic fibrosis who were screened for the commonest mutation (delta F 508) is presented. Six (46%) patients were homozygous for delta F 508, while two patients were compound heterozygotes. Thus 14 (53.8%) of 26 mutant chromosomes had delta F 508 mutation. These findings confirm that cystic fibrosis occurs in India and all children with persistent respiratory problems and/or malabsorption should be screened for this disease.
