J Clin Med 2023; 12:jcm12062403. [PMID: 36983403 PMCID: PMC10054146 DOI: 10.3390/jcm12062403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Revised: 03/15/2023] [Accepted: 03/20/2023] [Indexed: 03/30/2023] Open
Abstract
Asthma is caused by complex interactions between environmental and genetic factors. Various genes have been implicated as potential risk factors in the development of asthma; among them is cystic fibrosis transmembrane conductance regulator (CFTR) gene. The aim of this systematic review was to investigate the association of CFTR mutation heterozygosity with the development of asthma, by updating the existing data with recent studies' findings. Therefore, a systematic review of the literature was conducted on Pubmed, ESBCO (Cinahl) and Scopus Databases up to December 2022. After the eligibility assessment, 17 studies were included in this review. Nine of them supported a lack of relationship between CFTR mutation heterozygosity and asthma susceptibility, and eight reported a positive association. Consequently, more extensive research is needed through high-quality studies to provide valid evidence and highlight the clinical benefits of identifying CFTR mutations in asthma patients, their impact on asthma severity, or treatment perspectives.

Abstract
INTRODUCTION AND OBJECTIVES Asthma is a complex genetic disorder. Several genes have been found associated with asthma. The cystic fibrosis transmembrane conductance regulator (CFTR) gene is one of them. The aim of this study was to perform a comparative analysis of the genotype and allele frequency distributions of the biallelic marker M470V within the CFTR gene on mutant and wide chromosomes. PATIENTS AND METHODS The molecular approach consists in the genotyping of the M470V marker by the PCR-RFLP technique in 105 asthmatic patients, aged between four months and 17 years, and 105 healthy subjects. RESULTS We found a significant difference in the genotype frequencies between the two studied groups (χ2=9.855, P=0.007). The V/V genotype was over represented in the asthmatic group as compared to the controls (32.38% vs. 16.19%). Whereas, the M/V genotype is more frequent in healthy subjects (40.95% vs. 28.71%). We also noted a significant difference in allelic distribution of M470V with associated diseases (χ2=9.610, P=0.022). CONCLUSIONS The present study is the first report on the distribution of the M470V polymorphism in asthmatic Tunisian patients. We noticed that the M470V variant could modulate the clinical phenotype of asthmatic patients. This preliminary study will establish the molecular basis of this disease in Tunisia.

Abstract
BACKGROUND Patients with cystic fibrosis (CF) have a higher prevalence of asthma than the background population, however, it is unclear whether heterozygous CF carriers are susceptible to asthma. Given this, a meta-analysis is necessary to determine the veracity of the association of CF heterozygosity with asthma. METHODS We screened the medical literature from 1966 to 2015 and performed a meta-analysis to determine the risk of asthma in CF heterozygotes vs. non-carriers. RESULTS Aggregating data from 15 studies, the odds ratio for asthma in CF heterozygotes compared with non-carriers was significantly elevated at 1.61 (95% CI: 1.18-2.21). When analyzing the studies considered of high quality in which asthma was diagnosed by a physician, the patients were >18years, or study size was ≥500, the trend remained the same, that heterozygous carriers of CF had elevated risk for asthma. CONCLUSIONS The results show that heterozygous carriers for CF have a higher risk of asthma than non-carriers.

Abstract
Cystic Fibrosis Trans membrane conductance regulator (CFTR) gene is an asthma susceptibility gene. In the present study we investigated the possible association of CFTR gene mutations in Indian asthmatic children as compared to controls. The study included 250 asthmatics and 250 age and sex matched controls. Case to control ratio for sample size was 1:1. Genotyping was performed for 24 CFTR gene mutations by ARMS-PCR and PCR-RFLP method. Among 24 CFTR gene mutations, heterozygous allele of R553X mutation was found in 4 (1.6 %) asthmatic cases and 2 (0.8 %) controls. Value of FVC and FEV1/FVC ratio were significantly lower in heterozygous individuals (p value <0.05). No significant difference was observed in the genotype and allele frequency of R553X mutation (OR = 1.339, 95 % CI = 0.755-2.374, p value = 0.685). Furthermore, all wild type homozygous alleles were observed in remaining 23 CFTR gene mutations. Our data concludes that R553X mutation was not significantly associated in Indian asthmatic children.

Abstract
BACKGROUND Cystic fibrosis transmembrane conductance regulator (CFTR) gene accounts for an autosomal recessive condition called cystic fibrosis (CF). In the Indian subcontinent, CF and its related diseases are under-diagnosed by the medical community due to poor knowledge of the disease and its confounding diagnosis, and also due to poor medical facilities available for these patients, thus causing an increased infant mortality rate with a low life expectancy in general. The aim of the study was to document the spectrum and distribution of CFTR mutations in controls, asthma and chronic pancreatitis cases of North India. METHODS A total of 800 subjects including 400 controls, 250 asthma cases and150 chronic pancreatitis cases were analyzed for 6 mutations (F508del, G542X, G551D, R117H, W1282X, and S549N) and IVS8 Tn polymorphism. RESULTS Out of 800 subjects, 18% [asthma - 24% (n=250), CP - 29.33% (n=150) cases and controls - 9.3% (n=400)] were positive for heterozygous mutation, 0.8% of the (n=250) asthmatic cases (n=250) were homozygous for IVS8 T5 polymorphism while no subjects were found positive for W1282X mutation. T5 polymorphism was more common in asthmatic cases while F508del mutation in chronic pancreatitis cases. The carrier frequency of F508del, G542X, G551D, R117H, S549N and T5 was 0.015, 0.025, 0.02, 0.005, 0.005, and 0.022 respectively. The cumulative carrier frequency was 0.093. CONCLUSION CFTR mutations were underestimated in Indian population. The present study will serve in establishment of genetic screening and prenatal setup for Indian population.

Abstract
BACKGROUND Asthma is a complex genetic disorder. Several genes have been found associated with asthma. The cystic fibrosis transmembrane conductance regulator (CFTR) gene is one of them. AIM To assess the association of CFTR gene mutation with asthma and its severity as per GINA guidelines. SUBJECTS AND METHODS This was a hospital-based case-control study. Excluded from cases and controls were those with clinically suspected cystic fibrosis or sweat chloride level>60 mmol/L or suffering from other respiratory diseases. Included were 200 cases and 180 controls, aged 5 months to 15 years. Screening was done for CFTR gene mutations; ΔF508, G542X, G551D, R117H and W1282X using the ARMS-PCR method. RESULTS ΔF508 was found in three (1.5%) cases and two (1.1%) controls (p = 0.739), G542X in nine (4.5%) cases and five (2.8%) controls (p = 0.374), R117H in one (0.5%) case and one (0.6%) control (p = 0.940) and G551D in twelve (6.0%) cases and two (1.1%) controls (p = 0.012). Individuals carrier for G551D mutation had increased risk for persistent asthma (p = 0.006). Percent predicted FEV1 (p = 0.014) and FVC (p = 0.028) were significantly lower among carriers as compared to non-carriers. CONCLUSION Significantly higher frequency of G551D mutation among asthma patients compared with controls suggests that this mutation may increase risk for the disease and also its severity.

Abstract
BACKGROUND Cystic fibrosis transmembrane conductance regulator (CFTR) is an asthma susceptibility gene. Individuals heterozygous for CFTR gene mutation may develop obstructive pulmonary disease like bronchial asthma. AIM AND OBJECTIVE To find out the association of S549N and IVS8-5T variants of the CFTR gene with bronchial asthma and its severity and to assess the combinational effect of S549N and IVS8-5T variants on severity of disease. MATERIALS AND METHODS Included were 250 clinically diagnosed bronchial asthma cases aged 5 months to 15 years and 250 age- and sex-matched controls. All cases were further categorized into four different categories as per Global Initiative for Asthma criteria (GINA) guidelines: mild intermittent (83), mild persistent (96), moderate persistent (52), and severe persistent (19). Screening for S549N and 5T variants was done using the polymerase chain reaction-restriction fragment length polymorphism method. RESULT The proportion of IVS8-5T variant was found significantly higher in cases (10.8%) as compared with controls (2.4%) (p=0.001); however, no significant difference in the proportion of S549N was observed among cases (2.0%) and controls (0.8%) (p=0.447). Individuals mutant for IVS8-5T variant had increased risk for persistent asthma (p=0.000). DISCUSSION We conclude that IVS8-5T variant is associated with bronchial asthma and can also increase severity of the disease.

Abstract
Mutation on both the copies of cystic fibrosis transmembrane conductance regulator (CFTR) gene results in cystic fibrosis (CF), which is a recessively transmitted genetic disorder. It is hypothesized that individuals heterozygous for CFTR gene mutation may develop obstructive pulmonary diseases like asthma. There is great heterogeneity in the phenotypic presentation and severity of CF lung disease. This could be due to genetic or environmental factors. Several modifier genes have been identified which may directly or indirectly interact with CFTR pathway and affect the severity of disease. This review article discusses the information related to the association of CFTR gene mutation with asthma. Association between CFTR gene mutation and asthma is still unclear. Report ranges from studies showing positive or protective association to those showing no association. Therefore, studies with sufficiently large sample size and detailed phenotype are required to define the potential contribution of CFTR in the pathogenesis of asthma.
