Genes affected

VEGFC (HGNC:12682): (vascular endothelial growth factor C) The protein encoded by this gene is a member of the platelet-derived growth factor/vascular endothelial growth factor (PDGF/VEGF) family. The encoded protein promotes angiogenesis and endothelial cell growth, and can also affect the permeability of blood vessels. The proprotein is further cleaved into a fully processed form that can bind and activate VEGFR-2 and VEGFR-3 receptors. [provided by RefSeq, Apr 2014]

HAFML (HGNC:56694): (HuR (ELAVL1) associated fibroblast migratory lncRNA)

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 4-176687621-T-C is Benign according to our data. Variant chr4-176687621-T-C is described in ClinVar as Benign. ClinVar VariationId is 1231039.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.717 is higher than 0.05.
