Mutations in MPZ (P0)

For historical reason, the name of the mutation is based on the MPZ sequence D10537 (http://www.ncbi.nlm.nih.gov/entrez/) as published by Hayasaka et al., Biochem. Biophys. Res. Commun. 180, 515-518 (1991), and not the MPZ RefSeq NM_000530 ( http://www.ncbi.nlm.nih.gov/entrez/). In the first sequence the translation initiation codon is 30 nucleotides downstream of the one in the Refseq. The corresponding protein sequence is 10 amino acids shorter than the protein sequence derived from the MPZ RefSeq. However, the RefSeq record for MPZ has been updated on 03 May 2010 to now encode the 248 amino acid protein referred as NM_000530.6. The RefSeq NM_000530.6 should be considered when referring to MPZ mutations at the protein level.
