Pharmacogenetics of Pediatric Asthma: Current Perspectives

Area of Science:

• Pharmacogenetics
• Pediatric Respiratory Medicine
• Genomics

Background:

• Asthma affects millions globally, with significant impact on children.
• Pharmacological treatments exist but are ineffective for some pediatric asthma patients.
• Genetic variations play a role in individual responses to asthma therapies.

Purpose of the Study:

• To review pharmacogenetic studies on pediatric asthma treatment response published between 2018 and 2019.
• To update findings on gene associations with medication effectiveness in childhood asthma.

Main Methods:

• Systematic review of candidate-gene studies, meta-analyses, and pharmacogenomic studies.
• Analysis of genetic variations related to short-acting beta-agonists and inhaled corticosteroids response.

Main Results:

• Validated associations for genes like ADRB2, GSDMB, and VEGFA.
• Identified novel gene associations including PRKG1, DNAH5, and IL1RL1.
• Highlighted inconsistencies across studies, emphasizing the need for larger, diverse population research.

Conclusions:

• Genetic variants show promise as biomarkers for pediatric asthma treatment response.
• Further research is required to establish robust evidence for clinical application.
• Personalized medicine approaches can potentially improve asthma management and patient quality of life.
