Several factors contribute to the heterogeneity in neonatal disorders:
1. Genetics: Genetic mutations and variations can lead to a wide range of conditions, such as congenital heart defects and metabolic disorders. 2. Environmental Influences: Factors like maternal health, exposure to toxins, and prenatal care can significantly impact neonatal health. 3. Infections: Infections acquired during or after birth, such as neonatal sepsis, can vary in severity and impact. 4. Prematurity: Premature birth is a major contributor to heterogeneity, affecting organ development and increasing the risk of multiple complications.
