Is there a genetic test to catch an arnold chiari malformation early?

Not yet. Arnold chiari malformation can occur by itself or in association with other congenital abnormalities. There is no specific genetic test for arnold chiari yet.
AFP? The arnold chiari malformation is associated with spina bifida. In some pregnant women there can be elevation of the AFP that suggests such a risk. A high resolution ultrasound of the fetus can look for a spinal closure defect. Amniocentesis is more accurate but much more risky. Certain medications raise the risk of spina bifida - especially depakote. Use folate (folic acid) and get quality ultrasounds.

If I have an arnold chiari malformation, should I get genetic testing to check for other things?

Perhaps. If you have other birth defects (chiari can be secondary to spina bifida or be a part of syndromes), then chromosome testing may be indicated. Many chiari malformations occur alone, in which case genetic testing is not necessary. As genome sequencing becomes more rapid and available, genes conferring susceptibility to chiari and other isolated birth defects may become available for testing. Read more...

Complications with hydrocephalus and risk for seizures should also be checked out. Read more...

What are the tests for arnold-chiari malformation?

Head/ Cervical MRI. Chiari malformation is best diagnosed with a head MRI without contrast to assess for the abnormal tonsil position and determine whether hydrocephalus, or water on the brain, is present also. A cervical MRI without contrast can assess for a problem called a syrinx, or a fluid cavity in the center of the spinal cord. A lumbar MRI without contrast can also exclude a tethered cord causing numb legs. Read more...
