This is a list of variants' phenotypes submitted to ClinVar and linked to the SIAH1 gene.

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SIAH1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin- conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Mediates E3 ubiquitin ligase activity either through direct binding to substrates or by functioning as the essential RING domain subunit of larger E3 complexes. Triggers the ubiquitin-mediated degradation of many substrates, including proteins involved in transcription regulation (ELL2, MYB, POU2AF1, PML and RBBP8), a cell surface receptor (DCC), the cell-surface receptor-type tyrosine kinase FLT3, the cytoplasmic signal transduction molecules (KLF10/TIEG1 and NUMB), an antiapoptotic protein (BAG1), a microtubule motor protein (KIF22), a protein involved in synaptic vesicle function in neurons (SYP), a structural protein (CTNNB1) and SNCAIP. Confers constitutive instability to HIPK2 through proteasomal degradation. It is thereby involved in many cellular processes such as apoptosis, tumor suppression, cell cycle, axon guidance, transcription regulation, spermatogenesis and TNF-alpha signaling. Has some overlapping function with SIAH2. Induces apoptosis in cooperation with PEG3. Upon nitric oxid (NO) generation that follows apoptotic stimulation, interacts with S- nitrosylated GAPDH, mediating the translocation of GAPDH to the nucleus. GAPDH acts as a stabilizer of SIAH1, facilitating the degradation of nuclear proteins. {ECO:0000269|PubMed:10747903, ECO:0000269|PubMed:11146551, ECO:0000269|PubMed:11389839, ECO:0000269|PubMed:11389840, ECO:0000269|PubMed:11483517, ECO:0000269|PubMed:11483518, ECO:0000269|PubMed:11752454, ECO:0000269|PubMed:12072443, ECO:0000269|PubMed:14506261, ECO:0000269|PubMed:14645235, ECO:0000269|PubMed:14654780, ECO:0000269|PubMed:15064394, ECO:0000269|PubMed:16085652, ECO:0000269|PubMed:18536714, ECO:0000269|PubMed:19224863, ECO:0000269|PubMed:20508617, ECO:0000269|PubMed:22483617, ECO:0000269|PubMed:9334332, ECO:0000269|PubMed:9858595}.
