Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the HIF3A gene is commonly pathogenic or not. These statistics are base on transcript: NM_000152795.4. Only rare variants are included in the table.

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: Acts as a transcriptional regulator in adaptive response to low oxygen tension. Acts as a regulator of hypoxia-inducible gene expression (PubMed:11573933, PubMed:16126907, PubMed:19694616, PubMed:20416395, PubMed:21069422). Functions as an inhibitor of angiogenesis in hypoxic cells of the cornea. Plays a role in the development of the cardiorespiratory system. May also be involved in apoptosis (By similarity). {ECO:0000250|UniProtKB:Q0VBL6, ECO:0000269|PubMed:11573933, ECO:0000269|PubMed:16126907, ECO:0000269|PubMed:19694616, ECO:0000269|PubMed:20416395, ECO:0000269|PubMed:21069422}.; FUNCTION: Isoform 3: Attenuates the ability of transcription factor HIF1A to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation. {ECO:0000269|PubMed:19694616, ECO:0000269|PubMed:20416395, ECO:0000269|PubMed:21069422}.; FUNCTION: Isoform 5: Attenuates the ability of transcription factor HIF1A to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation. {ECO:0000269|PubMed:21069422}.;
