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

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.79G>C (p.A27P) alteration is located in exon 1 (coding exon 1) of the FOXC2 gene. This alteration results from a G to C substitution at nucleotide position 79, causing the alanine (A) at amino acid position 27 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
