Down syndrome chromosome region

Down syndrome, also known as trisomy 21, is the most frequent form of cognitive disability caused by a microscopically demonstrable chromosomal aberration. It is caused by a third copy (trisomy) of all or a critical portion of chromosome 21. Down syndrome is characterized by physical growth delays, dysmorphic facial features, heart and gastrointestinal disorders, and mild to moderate cognitive disability. [provided by RefSeq, Jul 2017]

Down syndrome critical region 8

Down syndrome critical region 3

The region of chromosome 21 between genes CBR and ERG (CBR-ERG region), which spans 2.5 Mb on 21q22.2, has been defined by analysis of patients with partial trisomy 21. It contributes significantly to the pathogenesis of many characteristics of Down syndrome, including morphological features, hypotonia, and cognitive disability. The DSCR3 (Down syndrome critical region gene 3) gene is found in this region and is predictated to contain eight exons. DSCR3 is expressed in most tissues examined. [provided by RefSeq, Jul 2008]

neural precursor cell expressed, developmentally down-regulated 8

Enables ubiquitin protein ligase binding activity. Acts upstream of or within protein neddylation. Located in cytosol and nucleoplasm. Biomarker of Parkinson's disease and malignant astrocytoma. [provided by Alliance of Genome Resources, Mar 2025]

neural precursor cell expressed, developmentally down-regulated 9

The protein encoded by this gene is a member of the CRK-associated substrates family. Members of this family are adhesion docking molecules that mediate protein-protein interactions for signal transduction pathways. This protein is a focal adhesion protein that acts as a scaffold to regulate signaling complexes important in cell attachment, migration and invasion as well as apoptosis and the cell cycle. This protein has also been reported to have a role in cancer metastasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

neural precursor cell expressed, developmentally down-regulated 1

Predicted to enable gamma-tubulin binding activity. Predicted to be involved in microtubule nucleation and mitotic cell cycle. Located in centrosome; cytosol; and nuclear lumen. [provided by Alliance of Genome Resources, Mar 2025]

nasopharyngeal carcinoma, down-regulated 1

Down syndrome critical region 3 pseudogene

IK cytokine, down-regulator of HLA II pseudogene

adenomatosis polyposis coli down-regulated 1-like

Predicted to enable Wnt-protein binding activity. Predicted to be involved in negative regulation of Wnt signaling pathway. Predicted to be located in plasma membrane. [provided by Alliance of Genome Resources, Mar 2025]

hepatocellular carcinoma, down-regulated 1

This gene is expressed predominantly in the liver. Transient transfection studies show the expression of this gene significantly inhibits cell growth, suggesting a role for this gene in apoptosis. Expression of this gene is down-regulated or lost in hepatocellular carcinomas (HCC), suggesting that loss of this gene is involved in carcinogenesis of hepatocytes (PMID:12971969). This gene maps to the 3'-noncoding region of the HEPACAM gene (GeneID:220296) on the antisense strand. [provided by RefSeq, Aug 2020]

neural precursor cell expressed, developmentally down-regulated 4-like, E3 ubiquitin protein ligase

This gene encodes a member of the Nedd4 family of HECT domain E3 ubiquitin ligases. HECT domain E3 ubiquitin ligases transfer ubiquitin from E2 ubiquitin-conjugating enzymes to protein substrates, thus targeting specific proteins for lysosomal degradation. The encoded protein mediates the ubiquitination of multiple target substrates and plays a critical role in epithelial sodium transport by regulating the cell surface expression of the epithelial sodium channel, ENaC. Single nucleotide polymorphisms in this gene may be associated with essential hypertension. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

neural precursor cell expressed, developmentally down-regulated 8 pseudogene

adenomatosis polyposis coli down-regulated 1

This locus encodes an inhibitor of the Wnt signaling pathway. Mutations at this locus have been associated with hereditary hypotrichosis simplex. Increased expression of this gene may also be associated with colorectal carcinogenesis.[provided by RefSeq, Sep 2010]

Down syndrome cell adhesion molecule

This gene is a member of the immunoglobulin superfamily of cell adhesion molecules (Ig-CAMs), and is involved in human central and peripheral nervous system development. This gene is a candidate for Down syndrome and congenital heart disease (DSCHD). A gene encoding a similar Ig-CAM protein is located on chromosome 11. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2012]

down-regulator of transcription 1, TBP-binding (negative cofactor 2)

This gene encodes a TBP- (TATA box-binding protein) associated phosphoprotein that represses both basal and activated levels of transcription. The encoded protein is phosphorylated in vivo and this phosphorylation affects its interaction with TBP. This protein contains a histone fold motif at the amino terminus, a TBP-binding domain, and a glutamine- and alanine-rich region. The binding of DR1 repressor complexes to TBP-promoter complexes may establish a mechanism in which an altered DNA conformation, together with the formation of higher order complexes, inhibits the assembly of the preinitiation complex and controls the rate of RNA polymerase II transcription.

Down syndrome critical region 9 (non-protein coding)

Down syndrome critical region 4

The gene is found in a region of chromosome 21 that has been linked to the pathogenesis of Down syndrome. This gene is transcribed from a bi-directional promoter located in an endogenous retrovirus. [provided by RefSeq, Jan 2015]

glioblastoma down-regulated RNA

leucine zipper, down-regulated in cancer 1

The protein encoded by this gene contains a leucine zipper-like motif and a proline-rich region that shares marked similarity with an SH3-binding domain. The protein localizes to the nucleus and is down-regulated in some cancer cell lines. It is thought to regulate the transcriptional response mediated by the nuclear factor kappa B (NF-kappaB). The gene has been proposed as a tumor suppressor gene whose protein product may have an important role in the development and/or progression of some cancers. [provided by RefSeq, Jul 2008]

Down syndrome critical region 10 (non-protein coding)

Down syndrome cell adhesion molecule like 1

The protein encoded by this gene is a member of the Ig superfamily of cell adhesion molecules and is involved in neuronal differentiation. The encoded membrane-bound protein localizes to the cell surface, where it forms aggregates that repel neuronal processes of the same cell type. [provided by RefSeq, Sep 2016]

leucine zipper, down-regulated in cancer 1-like

neural precursor cell expressed, developmentally down-regulated 4, E3 ubiquitin protein ligase

This gene is the founding member of the NEDD4 family of HECT ubiquitin ligases that function in the ubiquitin proteasome system of protein degradation. The encoded protein contains an N-terminal calcium and phospholipid binding C2 domain followed by multiple tryptophan-rich WW domains and, a C-terminal HECT ubiquitin ligase catalytic domain. It plays critical role in the regulation of a number of membrane receptors, endocytic machinery components and the tumor suppressor PTEN. [provided by RefSeq, Jul 2016]

IK cytokine, down-regulator of HLA II

The protein encoded by this gene was identified by its RED repeat, a stretch of repeated arginine, glutamic acid and aspartic acid residues. The protein localizes to discrete dots within the nucleus, excluding the nucleolus. Its function is unknown. This gene maps to chromosome 5; however, a pseudogene may exist on chromosome 2.
