Genes affected

TFAP2C (HGNC:11744): (transcription factor AP-2 gamma) The protein encoded by this gene is a sequence-specific DNA-binding transcription factor involved in the activation of several developmental genes. The encoded protein can act as either a homodimer or heterodimer with other family members and is induced during retinoic acid-mediated differentiation. It plays a role in the development of the eyes, face, body wall, limbs, and neural tube. [provided by RefSeq, Jul 2008]

The c.277C>A (p.P93T) alteration is located in exon 2 (coding exon 2) of the TFAP2C gene. This alteration results from a C to A substitution at nucleotide position 277, causing the proline (P) at amino acid position 93 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
