10 Causes of Geographic Tongue
Cause #9: Down Syndrome
Down syndrome is a genetic condition caused by the presence of a third copy of chromosome 21 (trisomy 21). This condition is associated with mild to moderate intellectual disability, delays in physical growth, and characteristic facial features. The parents of the patient are usually genetically normal. However, the chances of having a Down syndrome child increases to 3 percent once a woman reaches the age of 45 years old.
Down syndrome can be identified through prenatal screening and genetic testing. Although there is no cure for Down syndrome, the quality of life for those affected can be improved through care and specialized education. It is one of the commonest chromosomal anomalies in humans. Geographic tongue has also been associated with Down syndrome.
