Method for diagnosing amyotrophic lateral sclerosis using signal peptide as indicator

A method for aiding detection of amyotrophic lateral sclerosis (ALS), the method comprising:

• testing the presence or absence of an ALS-associated signal peptide in a bodily fluid from a test subject or the degree of abundance of the ALS-associated signal peptide when present, wherein
• the ALS-associated signal peptide is a signal peptide the presence or absence or degree of abundance of which in a bodily fluid from an ALS patient differs from the presence or absence or reference level set for degree of abundance of the same signal peptide in a bodily fluid from a healthy subject, and the molecular weight of the signal peptide is:
