Genes affected

FOXC2 (HGNC:3801): (forkhead box C2) This gene belongs to the forkhead family of transcription factors which is characterized by a distinct DNA-binding forkhead domain. The specific function of this gene has not yet been determined; however, it may play a role in the development of mesenchymal tissues. [provided by RefSeq, Jul 2008]

FOXC2-AS1 (HGNC:50665): (FOXC2 antisense RNA 1)

ACMG classification

Our verdict: Pathogenic. The variant received 18 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 49 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 16-86567632-C-G is Pathogenic according to our data. Variant chr16-86567632-C-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 7249.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
