REEP1 (Q9H902) variants and mutations

REEP1 (also known as Q9H902) is a human protein-coding gene encoding a receptor expression-enhancing protein 1 protein. It shapes tubular endoplasmic-reticulum membranes and supports interactions between the ER and neuronal cytoskeleton, particularly in long corticospinal axons. Pathogenic variants are a common cause of hereditary spastic paraplegia type 31 and can occasionally produce distal motor neuropathy. This analysis covers 348 REEP1 variants and mutations. Of these, 71% have computational variant effect predictions. Disease context includes Autosomal dominant spastic paraplegia type 31, hereditary spastic paraplegia 31, and neuronopathy, distal hereditary motor, type 5B. Example REEP1 variants include M1T, V2M, and W4G.
