Genes affected

EGLN1 (HGNC:1232): (egl-9 family hypoxia inducible factor 1) The protein encoded by this gene catalyzes the post-translational formation of 4-hydroxyproline in hypoxia-inducible factor (HIF) alpha proteins. HIF is a transcriptional complex that plays a central role in mammalian oxygen homeostasis. This protein functions as a cellular oxygen sensor, and under normal oxygen concentration, modification by prolyl hydroxylation is a key regulatory event that targets HIF subunits for proteasomal destruction via the von Hippel-Lindau ubiquitylation complex. Mutations in this gene are associated with erythrocytosis familial type 3 (ECYT3). [provided by RefSeq, Nov 2009]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acid is currently unknown. This variant has not been reported in the literature in individuals with EGLN1-related disease. This variant is not present in population databases (ExAC no frequency). This variant, c.122_124delACT, results in the deletion of 1 amino acid of the EGLN1 protein (p.Tyr41del), but otherwise preserves the integrity of the reading frame. -
