RAN proteins as biomarkers in CAG/CTG expansion disorders

Abstract

Aspects of the disclosure relate to methods and compositions (e.g., kits) for detecting certain repeat-associated non-ATG (RAN) proteins in a subject (e.g., a subject having or suspected of having a disease associated with a CAG and/or CTG repeat expansion). In some embodiments, methods described by the disclosure comprise detecting one or more RAN proteins in a biological sample obtained from a subject by an immunoassay using one or more antibodies that target homopolymeric repeat regions of RAN proteins. In some embodiments, the disclosure relates to kits comprising one or more antibodies that target homopolymeric repeat regions of RAN proteins, and an immunoassay plate and/or reagents. In some embodiments, the disclosure provides methods of producing anti-RAN protein antibodies.
