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: Uncertain_significance. The variant received 0 ACMG points.
