Diagnosis marker, diagnosis method and therapeutic agent for amyotrophic lateral sclerosis, and animal model and cell model developing amyotrophic lateral sclerosis

摘要

Provided are a diagnosis marker, a diagnosis method, and a therapeutic agent suitable for diagnosing and treating amyotrophic lateral sclerosis (ALS). Also provided are an animal model and a cell model suitable for developing a therapeutic agent and a treatment method for ALS. The diagnosis method for ALS includes: an isolation step in which a nucleic acid is isolated from a specimen taken from a subject; a detection step in which bases expressed in a human chromosome 10 optineurin (OPTN) gene region are detected from the isolated nucleic acid; and a determination step in which it is determined whether or not the detected bases are mutated.

主权项

1. A method for diagnosing amyotrophic lateral sclerosis in a human subject, comprising:
(a) obtaining a sample from a human subject suspected of amyotrophic lateral sclerosis, (b) isolating nucleic acids from the sample, (c) amplifying DNA fragments from exon 12 of the OPTN (Optineurin) gene by polymerase chain reaction using primers having the sequence of SEQ ID NO: 5 and 6, (d) determining whether the base in exon 12 of the OPTN at position 13207995 of chromosome 10 is mutated, and (e) diagnosing that the subject has amyotrophic lateral sclerosis if the base is mutated.
