SQSTM1 (Sequestosome-1) variants and mutations

SQSTM1 (also known as Sequestosome-1) is a human protein-coding gene encoding a sequestosome-1 protein. SQSTM1, also called p62, is an adapter that connects ubiquitinated cargo to autophagosomes for selective autophagy. It also influences the NRF2 cytoprotective pathway and endosomal organization, and SQSTM1 variants are associated with Paget disease of bone and neurodegeneration. This analysis covers 987 SQSTM1 variants and mutations. Of these, 94% have computational variant effect predictions. Disease context includes amyotrophic lateral sclerosis, behavioral variant of frontotemporal dementia, and frontotemporal dementia with motor neuron disease. Example SQSTM1 variants include M1?, M1I, and M1K.
