    Summary
    This gene is specifically expressed in Schwann cells of the peripheral nervous system and encodes a type I transmembrane glycoprotein that is a major structural protein of the peripheral myelin sheath. The encoded protein contains a large hydrophobic extracellular domain and a smaller basic intracellular domain, which are essential for the formation and stabilization of the multilamellar structure of the compact myelin. Mutations in this gene are associated with autosomal dominant form of Charcot-Marie-Tooth disease type 1 (CMT1B) and other polyneuropathies, such as Dejerine-Sottas syndrome (DSS) and congenital hypomyelinating neuropathy (CHN). A recent study showed that two isoforms are produced from the same mRNA by use of alternative in-frame translation termination codons via a stop codon readthrough mechanism.

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      Status: REVIEWED

      Description
      Transcript Variant: This transcript (1) encodes two isoforms, which result from the use of alternative in-frame translation termination codons. The shorter isoform (MPZ, also known as P0) results from translation termination at the upstream UAG stop codon, while the longer isoform (L-MPZ) results from UAG stop codon readthrough to the downstream UGA termination codon. This RefSeq represents the shorter isoform (MPZ).

      Transcript Variant: This transcript (1) encodes two isoforms, which result from the use of alternative in-frame translation termination codons. The shorter isoform (MPZ, also known as P0) results from translation termination at the upstream UAG stop codon, while the longer isoform (L-MPZ) results from UAG stop codon readthrough to the downstream UGA termination codon. This RefSeq represents the longer, C-terminally extended isoform (L-MPZ). As the UAG stop codon has been reported to specify several alternative amino acids (glutamine, tyrosine and leucine), its location in the longer isoform is denoted by an 'X'.
