Summary: 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 cognitive disability of Down syndrome.

no gene harboring deletions were identified in the SIM1 and MRAP2 regions in the Prader Willi like (PWL) cohort; further functional analysis of p.P352S found in SIM1 and p.A40S found in MRAP2 is useful; this would provide further support for possible role of SIM1 and MRAP2 in the pathogenesis of the PWL phenotype in a limited number of patients

RefSeqs maintained independently of Annotated Genomes

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.
