Abstract
The invention provides compositions and methods for identifying autism and autism spectrum disorders in humans. The invention also includes compositions and methods for identifying unique gene expression profiles in children with regressive autism spectrum disorder (ASD) and ileocolitis.
Claims2
A method of treating a gastrointestinal disorder selected from the group consisting of ileocolitis, ileitis, and colitis, in a human child, wherein said child has an autism spectrum disorder, the method comprising
- obtaining a biological sample from the colon or ileum of the child by ileocolonoscopy;
- immediately storing the biological sample in RNA stabilizer solution;
- freezing the biological sample within 48 hours;
- measuring the level of IGF2BP1 RNA transcripts in the biological sample,
- wherein an increase in the level of IGF2BP1 RNA transcripts in the biological sample relative to the level of IGF2BP1 RNA transcripts in a control indicates that the child has or is at risk of having a gastrointestinal disorder;
- and
- administering a treatment for the gastrointestinal disorder to the child with the gastrointestinal disorder.
A method of treating a gastrointestinal disorder selected from the group consisting of ileocolitis, ileitis, and colitis, in a human child, wherein said child has an autism spectrum disorder, the method comprising
- obtaining a biological sample from the colon or ileum of the child by ileocolonoscopy;
- immediately storing the biological sample in RNA stabilizer solution;
- freezing the biological sample within 48 hours;
- measuring the level of TNFRSF12A RNA transcripts in the biological sample,
- wherein for the biological sample obtained from the colon, an increase in the level of TNFRSF12A RNA transcripts relative to the level of TNFRSF12A RNA transcripts in a control indicates that the child has or is at risk of having a gastrointestinal disorder;
- wherein for the biological sample obtained from the ileum, decrease in the level of TNFRSF12A RNA transcripts relative to the level of TNFRSF12A RNA transcripts in a control indicates that the child has or is at risk of having a gastrointestinal disorder;
- and
- administering a treatment for the gastrointestinal disorder to the child with the gastrointestinal disorder.
