Genes affected

ANKRD12 (HGNC:29135): (ankyrin repeat domain 12) This gene encodes a member of the ankyrin repeats-containing cofactor family. These proteins may inhibit the transcriptional activity of nuclear receptors through the recruitment of histone deacetylases. The encoded protein interacts with p160 coactivators and also represses transcription mediated by the coactivator alteration/deficiency in activation 3 (ADA3). Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2011]

The c.1736A>T (p.D579V) alteration is located in exon 9 (coding exon 8) of the ANKRD12 gene. This alteration results from a A to T substitution at nucleotide position 1736, causing the aspartic acid (D) at amino acid position 579 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
