SOX10 regulates an alternative promoter at the Charcot-Marie-Tooth disease locus MTMR2.

ABSTRACT: Schwann cells are the myelinating glia of the peripheral nervous system and dysfunction of these cells causes motor and sensory peripheral neuropathy. The transcription factor SOX10 is critical for Schwann cell development and maintenance, and many SOX10 target genes encode proteins required for Schwann cell function. Loss-of-function mutations in the gene encoding myotubularin-related protein 2 (MTMR2) cause Charcot-Marie-Tooth disease type 4B1 (CMT4B1), a severe demyelinating peripheral neuropathy characterized by myelin outfoldings along peripheral nerves. Previous reports indicate that MTMR2 is ubiquitously expressed making it unclear how loss of this gene causes a Schwann cell-specific phenotype. To address this, we performed computational and functional analyses at MTMR2 to identify
