Fetal Alcohol syndrome (FAS)

What is Fetal Alcohol syndrome (FAS)?

Fetal Alcohol syndrome is caused when a fetus is exposed to alcohol during the pregnancy. It causes damage to both growth and brain development.

Characteristics of the syndrome include distinct and unique facial features, a short stature, low weight at birth and continued low growth, as well as issues with coordination, learning and development.

What gene changes cause Fetal Alcohol syndrome (FAS)?

The syndrome is caused by exposure to the fetus to alcohol during pregnancy. The effects are irreversible and may vary in their severity.

Environmental causes, or exposure to external environmental factors, can sometimes contribute to the cause of a rare disease.

What are the main symptoms of Fetal Alcohol syndrome (FAS)?

The main symptoms of the syndrome include a low birth weight and a failure to thrive that affects growth development. Behavioral and learning issues are also a major symptom including hyperactivity, impulsiveness, and anxiety.

Facial and physical characteristics include a short stature, small eye openings, a thin upper lip and smooth philtrum.

Other health conditions may include heart, bone and kidney problems. Issues with vision and hearing, seizures, poor balance and coordination.

How does someone get tested for Fetal Alcohol syndrome (FAS)?

The initial testing for Fetal Alcohol syndrome can begin with facial analysis screening, through the FDNA Telehealth telegenetics platform, which can identify the key markers of the syndrome and outline the need for further testing. A consultation with a genetic counselor and then a geneticist will follow. 

Based on this clinical consultation with a geneticist, the different options for genetic testing will be shared and consent will be sought for further testing.
