Biallelic CHCHD2 variants are rare. We report a consanguineous man with a novel homozygous CHCHD2 c.395A>T (p.Lys132Met) variant who developed progressive cognitive decline, apraxia, oculomotor impairment, and pyramidal signs without parkinsonism. Clinicians should consider CHCHD2 in familial dementia with pyramidal signs, even when motor parkinsonism is absent.
