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:54284): (HIF1A antisense RNA 3)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.180G>A (p.M60I) alteration is located in exon 2 (coding exon 2) of the HIF1A gene. This alteration results from a G to A substitution at nucleotide position 180, causing the methionine (M) at amino acid position 60 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
