Occasionally, MORC2 mutations produce early‐onset spinal muscular atrophy‐like (SMA‐like) phenotypes characterized by proximal muscle and atrophy without sensory loss with or without diaphragmatic palsy (Schottmann et al., 2016; Zanni et al., 2017), microcephaly (Sevilla et al., 2016; Zanni et al., 2017), or cerebellar atrophy (Schottmann et al., 2016). Here, MORC2 is linked to spinal muscular atrophy.
