Genes affected
TFAP2D (HGNC:15581): (transcription factor AP-2 delta) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in anatomical structure development; regulation of cell population proliferation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within inferior colliculus development; negative regulation of neuron apoptotic process; and positive regulation of transcription by RNA polymerase II. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.1262C>T (p.A421V) alteration is located in exon 8 (coding exon 8) of the TFAP2D gene. This alteration results from a C to T substitution at nucleotide position 1262, causing the alanine (A) at amino acid position 421 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
