INSM2
protein-codingINSM transcriptional repressor 2, the group of SNAG transcriptional repressors|Zinc fingers C2H2-type
Gene summary
Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II; neuron differentiation; and regulation of cell cycle process. Predicted to be located in cytoplasm. Predicted to be part of transcription repressor complex. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Jul 2025]

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_032594.4. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
