Clinical Description

Congenital malformation syndromes encompass a variety of conditions characterized by structural anomalies that can affect multiple organ systems. The designation "other congenital malformation syndromes due to known exogenous causes" indicates that these syndromes arise from identifiable external factors that influence fetal development.

Exogenous Causes

Exogenous factors are external agents that can lead to congenital malformations. These may include:

• Teratogenic substances: These are drugs, chemicals, or environmental agents that can cause malformations when a fetus is exposed during critical periods of development. Examples include:
• Alcohol: Maternal alcohol consumption can lead to Fetal Alcohol Spectrum Disorders (FASD), which are characterized by growth deficiencies, facial dysmorphisms, and neurodevelopmental issues[4].
• Antiepileptic drugs: Medications such as phenytoin (Dilantin) and valproate can cause specific malformation syndromes when taken during pregnancy[10].

• Warfarin: Exposure to this anticoagulant can result in characteristic dysmorphic features and other anomalies[9].

• Infectious agents: Certain infections during pregnancy, such as rubella or cytomegalovirus, can also lead to congenital malformations[6].

• Nutritional deficiencies: Lack of essential nutrients, such as folic acid, can result in neural tube defects and other malformations[5].

Clinical Features

The clinical presentation of congenital malformation syndromes due to known exogenous causes can vary widely depending on the specific agent involved and the timing of exposure during pregnancy. Common features may include:

• Growth retardation: Infants may be smaller than expected for their gestational age.
• Facial dysmorphisms: Distinctive facial features may be present, such as a smooth philtrum, thin upper lip, and small palpebral fissures in cases of FASD.
• Neurological deficits: Cognitive impairments and developmental delays are often associated with these syndromes.
• Organ-specific anomalies: Depending on the teratogen, various organ systems may be affected, leading to congenital heart defects, limb malformations, or renal anomalies.

Diagnosis and Management

Diagnosis

Diagnosis of congenital malformation syndromes typically involves:

• Clinical evaluation: A thorough physical examination to identify characteristic features.
• Medical history: Detailed maternal history to ascertain potential exposures to teratogens during pregnancy.
