Research on the relativity between gene polymorphism and children cardiac insufficiency

Area of Science:

• Genetics
• Pediatrics
• Cardiology

Background:

• Cardiac insufficiency in children is a significant health concern.
• Understanding genetic predispositions is crucial for early diagnosis and intervention.
• The role of specific gene polymorphisms in pediatric cardiac conditions requires further investigation.

Purpose of the Study:

• To investigate the association between Mink-S27 gene polymorphism and cardiac insufficiency in children.
• To determine if Mink-S27 genotype and allele frequencies differ between children with and without cardiac insufficiency.
• To explore the correlation between Mink-S27 polymorphism and the severity of cardiac insufficiency.

Main Methods:

• A case-control study involving 73 children with cardiac insufficiency (observation group) and 76 healthy children (control group).
• Restriction fragment length polymorphism (RFLP) was employed for Mink-S27 gene polymorphism analysis.
• Genotype and allele frequencies were compared between the groups, with a focus on lesion samples and disease severity.

Main Results:

• No significant differences in overall Mink-S27 genotype and allele distribution were observed between the cardiac insufficiency and control groups (p>0.05).
• Significant differences in AA and CC genotype frequencies and allele distribution were found in lesion samples from children with cardiac insufficiency compared to controls (p<0.05).
• A higher proportion of homozygotes (AA, CC) was noted in children with severe cardiac insufficiency, indicating a correlation with disease severity.

Conclusions:

• GNAS2 gene polymorphism is associated with the prevalence of cardiac insufficiency in children.
• The frequency of different Mink-S27 genotypes and alleles correlates with the patients' cardiac insufficiency condition and severity.
• Further research into GNAS2 gene's role may offer insights into pediatric cardiac disease mechanisms.
