Genes affected

TFAP2A (HGNC:11742): (transcription factor AP-2 alpha) The protein encoded by this gene is a transcription factor that binds the consensus sequence 5'-GCCNNNGGC-3'. The encoded protein functions as either a homodimer or as a heterodimer with similar family members. This protein activates the transcription of some genes while inhibiting the transcription of others. Defects in this gene are a cause of branchiooculofacial syndrome (BOFS). Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Dec 2009]

TFAP2A-AS1 (HGNC:40579): (TFAP2A antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BP6: Variant 6-10409955-T-G is Benign according to our data. Variant chr6-10409955-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 2656219.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.515 with no splicing effect.
