Definitions
- the present invention relates to a method for diagnosis of autism by means of a simple test on a sample of a subject.
- Autism is the term for a symptom-complex of a subject meaning such a bad communication possibility with people around that the subject in question has to be taken care of by the society in different ways during its whole lifetime.
- the pathophysiology of autism involves abnormal communication between neurons, possibly associated with abnormal patterns peptides, e.g., neuropeptides in the brain.
- Abnormal levels of peptides might be revealed by proteomic studies of proteins/peptides below 10 kDa in spinal fluid and/or blood plasma. Detection of abnormal levels of peptides in autism will allow generation of new hypotheses concerning its pathophysiology and might facilitate diagnostics and suggest new treatment possibilities. Since most peptides are generated by proteolysis of larger precursor molecules abnormal levels of peptides might be caused by abnormal proteolytic activity.
- EP-A-0 979 828 discloses a method for diagnosing autism by determining specific peptides present in a biological fluid.
- the peptides which comprises 3 to 4 amino acids are said to indicate autism when present in high amounts.
- EP-A-0 969 015 relates to a method for diagnosing a disease, such as autism, by identifying peptides present in a tissue of body liquid.
- the peptides are disclosed as having a length of 3 to 8 amino acids, and having a molecular weight of ⁇ 1081.
- the amount of oxytocin-extened (OT-X) is higher in autistic patients, while the amount of oxytocin (9 amino acids) is lower.
- US-A-2002/0006640 relates polypeptides and methods for diagnosis of inter alia autism.
- the present invention is based on a hypothesis that the basis of autism is the presence of an abnormal peptide pattern in the brain and/or the fluids penetrating or surrounding the brain, i.e., blood and cerebrospinal fluid, and that some of these peptides might disturb the signals (e.g., carried neuropeptides), used by the brain for communication.
- the invention is characterized in the determination of the presence or absence of certain proteins/peptides with specific amino acids sequences, present in a body sample, which proteins/peptides have the molecular masses of 1779 +/- 1 Da, 1865 +/- 1 Da and 2022 +/- 1 Da, respectively.
- the present invention relates to determining in a tissue sample, body liquid and/or plasma sample a higher than normal level of one or more of the following peptides
- the amount of the peptide(s) is more than 10 times that present in a sample of a healthy subject.
- the respective peptide is determined using ELISA technology.
- the respective peptide is determined using RIA technology.
- the respective peptide is determined using a SELDI-TOF-MS system.
- kits for determining said peptides whereby the kit comprises a marker for certain peptides having the molecular weights 1779, 1865 and 2022, respectively.
- it comprises a marker for one or more of the peptides encoded for by the amino acid sequence SSKITHRIHWESASLLR, SSKITHRIHWESASLL, and/or SKITHRIHWESASLL.
- Body liquid means herein any body liquid such as blood, blood serum, blood plasma, spinal fluid, cerebrospinal fluid, and lymph.
- the present peptides may be a fragment of a plasma protein called complementary factor C3.
- FIG. 1 shows eight different mass spectrometry profiles in the 1700 to 2200 Dalton band obtained from eight individuals, four without a diagnosis of autism and four diagnosed as autistic children.
- the upper four are mass spectrometry bands from the individuals without a diagnosis of autism, and the lower four are from the autistic children. It is apparent that there are at least three different peaks appearing in the samples of the autistic children that differ considerably from those of children without a diagnosis of autism.
- appropriate molecular mass markers it is determined that at about 1779, 1865 and 2022 Daltons there are significant peaks present.
- the different peak areas represent amounts of the respective peptide present which amounts are more than ten times higher in samples from autistic children than in samples from children without a diagnosis of autism.
- the structures of the peptides were determined using MS/MS mass spectrometry, whereby their amino acid sequences were determined to be SSKITHRIHWESASLLR (SEQ. ID. NO. 1), SSKITHRIHWESASLL (SEQ. ID. NO. 3), and SKITHRIHWESASLL (SEQ. ID. NO. 3), respectively.
- the first peptide is known as complement C3f (NCBI accession number 1413205A), the second one lacks C-terminal arginine, and the third one further lacks N-terminal serine.
- concentrations of the selected peptides in e.g., plasma or spinal fluid samples can easily be determined by means of immunochemical techniques, such as ELISA or RIA.
- Antibodies will be used and labelling of antibodies and/or the antigen peptides will be performed according to general protocols using e.g., the chloramine T method for radiolabelling.
