Summaries for SIM1 Gene

Entrez Gene Summary for SIM1 Gene

  • SIM1 and SIM2 genes are Drosophila single-minded (sim) gene homologs. SIM1 transcript was detected only in fetal kidney out of various adult and fetal tissues tested. Since the sim gene plays an important role in Drosophila development and has peak levels of expression during the period of neurogenesis,it was proposed that the human SIM gene is a candidate for involvement in certain dysmorphic features (particularly the facial and skull characteristics), abnormalities of brain development, and/or mental retardation of Down syndrome.

GeneCards Summary for SIM1 Gene

SIM1 (Single-Minded Family BHLH Transcription Factor 1) is a Protein Coding gene. Diseases associated with SIM1 include prader-willi-like syndrome associated with chromosome 6 and obesity, sim1-related. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and signal transducer activity. An important paralog of this gene is AHRR.
