Genes affected

HIF1A (HGNC:4910): (hypoxia inducible factor 1 subunit alpha) This gene encodes the alpha subunit of transcription factor hypoxia-inducible factor-1 (HIF-1), which is a heterodimer composed of an alpha and a beta subunit. HIF-1 functions as a master regulator of cellular and systemic homeostatic response to hypoxia by activating transcription of many genes, including those involved in energy metabolism, angiogenesis, apoptosis, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. HIF-1 thus plays an essential role in embryonic vascularization, tumor angiogenesis and pathophysiology of ischemic disease. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Jul 2011]

HIF1A-AS3 (HGNC:):

HIF1A-AS3 (HGNC:54284): (HIF1A antisense RNA 3)

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BP6: Variant 14-61740835-G-A is Benign according to our data. Variant chr14-61740835-G-A is described in ClinVar as [Benign]. Clinvar id is 716776.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.117 with no splicing effect.
• BS2: High AC in GnomAd4 at 306 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
