Condition	Inheritance	Intervention Categories	Intervention/Rationale	Manifestation Categories	References
Erthyrocytosis, familial 4	AD	Hematologic; Oncologic	Individuals can present with manifestations secondary to erythrocytosis (eg, a DVT has been described in one individual), and interventions related to erythrocytosis (eg, venesection) have been described as beneficial; Due to a reported increased risk of neoplasms (eg, pheochromocytoma/paraganglioma), awareness may allow early detection and management, which may decrease associated morbidity and mortality	Hematologic; Oncologic	7747773; 18184961; 18456918; 18378852; 23090011

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the EPAS1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Transcription factor involved in the induction of oxygen regulated genes. Heterodimerizes with ARNT; heterodimer binds to core DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of target gene promoters (By similarity). Regulates the vascular endothelial growth factor (VEGF) expression and seems to be implicated in the development of blood vessels and the tubular system of lung. May also play a role in the formation of the endothelium that gives rise to the blood brain barrier. Potent activator of the Tie-2 tyrosine kinase expression. Activation requires recruitment of transcriptional coactivators such as CREBBP and probably EP300. Interaction with redox regulatory protein APEX seems to activate CTAD (By similarity). {ECO:0000250, ECO:0000250|UniProtKB:P97481}.
• Disease: DISEASE: Erythrocytosis, familial, 4 (ECYT4) [MIM:611783]: An autosomal dominant disorder characterized by increased serum red blood cell mass, elevated serum hemoglobin and hematocrit, and normal platelet and leukocyte counts. {ECO:0000269|PubMed:18184961, ECO:0000269|PubMed:18378852, ECO:0000269|PubMed:19208626, ECO:0000269|PubMed:22367913}.
