Mis-births, also known as congenital anomalies, birth defects or developmental disorders, refer to any structural or functional abnormalities present at birth. Synonyms for mis-births can include malformations, deformities, abnormalities, anomalies, or disorders. These terms can encompass a wide range of conditions, from minor physical malformations to life-threatening conditions. Mis-births can have various causes, including genetic factors, environmental factors, or a combination of both. It is important to note that not all congenital abnormalities are preventable, however, proper prenatal care, genetic counseling and environmental precautions can help reduce the risk of mis-births. Early diagnosis and treatment can also improve the quality of life for individuals with congenital anomalies.
