• chr19-40801179-G-A
• NM_080732.4:c.607G>A

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_053046.4(EGLN2):​c.607G>A​(p.Gly203Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G203G) has been classified as Likely benign.

Genes affected

EGLN2 (HGNC:14660): (egl-9 family hypoxia inducible factor 2) The hypoxia inducible factor (HIF) is a transcriptional complex that is involved in oxygen homeostasis. At normal oxygen levels, the alpha subunit of HIF is targeted for degration by prolyl hydroxylation. This gene encodes an enzyme responsible for this post-translational modification. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the upstream RAB4B (RAB4B, member RAS oncogene family) gene.

RAB4B-EGLN2 (HGNC:44465): (RAB4B-EGLN2 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring RAB4B (RAB4B, member RAS oncogene family) and EGLN2 (egl nine homolog 2) genes on chromosome 19. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
