Genes affected

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

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 Gene-Disease associations (from GenCC):

• branchiooculofacial syndrome

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 6-10419865-C-T is Benign according to our data. Variant chr6-10419865-C-T is described in ClinVar as Benign. ClinVar VariationId is 1287998.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.26 is higher than 0.05.
