Genes affected

FOXF2 (HGNC:3810): (forkhead box F2) FOXF2 encodes forkhead box F2, one of many human homologues of the Drosophila melanogaster transcription factor forkhead. FOXF2 is expressed in lung and placenta, and has been shown to transcriptionally activate several lung-specific genes. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.44).
• BP6: Variant 6-1390187-C-T is Benign according to our data. Variant chr6-1390187-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3044929.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP7: Synonymous conserved (PhyloP=1.32 with no splicing effect.
