    Area of Science:

    • Medical Genetics
    • Developmental Biology
    • Public Health

    Background:

    • Congenital malformations and genetic disorders are increasing causes of early morbidity and mortality in Western societies, surpassing infectious diseases.
    • These conditions represent a significant public health challenge, accounting for 25-30% of pediatric hospital admissions and affecting 3-4% of all births.
    • The etiology of many congenital malformations and cases of mental retardation remains unclear in approximately two-thirds of instances.

    Purpose of the Study:

    • To explore the influence of environmental factors on the development of congenital malformations.
    • To provide a comprehensive perspective on the multifactorial etiology of birth defects.

    Main Methods:

    • Review of existing literature on congenital malformations and genetic disorders.
    • Analysis of epidemiological data on the prevalence of these conditions.
    • Discussion of the interplay between genetic and environmental influences.

    Main Results:

    • Over 3,000 genetic disorders have been identified, with many resulting from gene-environment interactions.
    • Environmental factors are suspected contributors to a significant proportion of congenital malformations.
    • Understanding these interactions is key to addressing the burden of these disorders.

    Conclusions:

    • Environmental factors play a critical role in the etiology of congenital malformations.
    • Further research into gene-environment interactions is essential for prevention and treatment strategies.
    • Addressing congenital malformations requires a multifaceted public health approach.
