Subsequent reports have revealed that mutations in MORC2 can present a wide range of phenotypes7; heterozygous mutations in MORC2 can cause spinal muscular atrophy-like (SMA-like) phenotypes and developmental delay, impaired growth, dysmorphic facies, and axonal neuropathy (DIGFAN) phenotypes, both of which develop earlier than CMT2Z7. Here, MORC2 is linked to axonal neuropathy.
