Alterations in proteins that regulate endoplasmic reticulum morphology are common causes of hereditary spastic paraplegia (SPG1‐78, plus others). Mutations in the REEP1 gene that encodes an endoplasmic reticulum‐shaping protein are well‐known causes of SPG31, a common autosomal dominant spastic paraplegia. A closely‐related gene, REEP2, is mutated in SPG72, with both autosomal and recessive inheritances. Here, we report a patient with a pure hereditary spastic paraplegia due to a de novo missense mutation (c.119T > G, p.Met40Arg) in REEP2 at a highly‐conserved residue very close to another known pathogenic missense change. This represents only the second autosomal dominant SPG72 missense mutation reported.
