Gene Gene information from NCBI Gene database.
Entrez ID 3508
Gene name Immunoglobulin mu DNA binding protein 2
Gene symbol IGHMBP2
Synonyms (NCBI Gene)
CATF1CMT2SHCSAHMN6HMNR1SMARD1SMUBP2ZFAND7
Chromosome 11
Chromosome location 11q13.3
Summary This gene encodes a helicase superfamily member that binds a specific DNA sequence from the immunoglobulin mu chain switch region. Mutations in this gene lead to spinal muscle atrophy with respiratory distress type 1. [provided by RefSeq, Jul 2008]
