Insights
Cystic fibrosis (CF) is rarely seen in American Indians, but three Pueblo children were diagnosed. This suggests a higher incidence in this population, warranting increased awareness.
Area of Science:
- Genetics
- Pediatrics
- Epidemiology
Background:
- Cystic fibrosis (CF) is a rare genetic disorder.
- Previous data indicate a low incidence of CF in American Indian populations.
Observation:
- Three cases of cystic fibrosis were identified in Pueblo American Indian children.
- This represents a higher observed incidence than previously documented for this demographic.
Findings:
- The incidence of cystic fibrosis among Pueblo Indians may be higher than expected.
- Genetic factors could contribute to this observed frequency.
Implications:
- Clinicians should consider cystic fibrosis in American Indian children presenting with relevant symptoms.
- Further genetic research is needed to understand CF prevalence in indigenous populations.
Abstract:
Three Pueblo American Indian children with cystic fibrosis are described. The three cases constitute a higher incidence of cystic fibrosis in Pueblo Indians than would be expected from the known rarity of this disease in American Indian populations. This report discusses the possible genetic implications and emphasizes the need to consider the diagnosis of cystic fibrosis in American Indians with appropriate symptoms.
