Evidence indicates that these levels are associated with infant neurological abnormalities. VSDs are the most common congenital cardiac abnormalities. Cardiac surgery is often required for congenital heart abnormalities. This disorder consists of a spectrum of defects, malformations and associated abnormalities. The model attempts to relate specific symptoms of depression to neurological abnormalities. Each also has "classic" blood test abnormalities and abnormal antibody patterns. An increased thickness corresponds to increased risk for aneuploidy and other fetal abnormalities. Induced abnormalities in thyroid function are common. Most of the congentital abnormalities were mild deformities. People with certain metabolic abnormalities, including obesity, may produce uric acid stones. Such frameworks have hypothesized links between these biological abnormalities and symptoms. CGH is only able to detect unbalanced chromosomal abnormalities. Other abnormalities may be associated with this, including cardiac abnormalities, or VACTERL syndrome. Other symptoms include disturbances to posture, fatigue, sleep abnormalities, and depressed mood. TNF-/- mice develop normally and have no gross structural or morphological abnormalities.
