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]

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 97 of the TFAP2A protein (p.Pro97Ser). This variant is present in population databases (rs746489683, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with TFAP2A-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
