Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_Moderate BP7 BS2

The NM_001372066.1(TFAP2A):​c.768G>C​(p.Arg256Arg) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000626 in 1,597,378 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. R256R) has been classified as Likely benign.

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-AS2 (HGNC:52289): (TFAP2A antisense RNA 2) The product of this intronless gene is a capped lncRNA that is nuclear-enriched and associated with chromatin. The encoded transcript may be involved in the regulation of developmental gene expression in a context-dependent manner, functioning as a repressor in non-pluripotent cells and an activator in pluripotent cells. Transcription of this gene is activated in 8-cell human embryos during the major wave of zygotic genome activation, independently of and prior to the activation of TFAP2A, an overlapping gene found on the opposite strand. Expression of this gene is characterized by high cell-to-cell variability in the cells of totipotent human embryos and in stable cell lines. [provided by RefSeq, Mar 2017]

ACMG classification

Our verdict: Benign. The variant received -7 ACMG points.

• BP4: Computational evidence support a benign effect (REVEL=0.163).
• BP7: Synonymous conserved (PhyloP=0.041 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 8 AD gene.
