Genes affected

EPAS1 (HGNC:3374): (endothelial PAS domain protein 1) This gene encodes a transcription factor involved in the induction of genes regulated by oxygen, which is induced as oxygen levels fall. The encoded protein contains a basic-helix-loop-helix domain protein dimerization domain as well as a domain found in proteins in signal transduction pathways which respond to oxygen levels. Mutations in this gene are associated with erythrocytosis familial type 4. [provided by RefSeq, Nov 2009]

LINC01820 (HGNC:52625): (long intergenic non-protein coding RNA 1820)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.301 is higher than 0.05.
