Summaries for KCTD1 Gene

Entrez Gene Summary for KCTD1 Gene

  • This gene encodes a protein containing a BTB (Broad-complex, tramtrack and bric a brac), also known as a POZ (POxvirus and zinc finger) protein-protein interaction domain. The encoded protein negatively regulates the AP-2 family of transcription factors and the Wnt signaling pathway. A mechanism for the modulation of Wnt signaling has been proposed in which the encoded protein enhances ubiquitination and degradation of the beta-catenin protein. Mutations in this gene have been identified in Scalp-ear-nipple (SEN) syndrome. [provided by RefSeq, May 2017]

GeneCards Summary for KCTD1 Gene

KCTD1 (Potassium Channel Tetramerization Domain Containing 1) is a Protein Coding gene. Diseases associated with KCTD1 include Scalp-Ear-Nipple Syndrome and Subependymal Glioma. Among its related pathways are Gene Expression and Transcriptional regulation by the AP-2 (TFAP2) family of transcription factors. Gene Ontology (GO) annotations related to this gene include transcription factor binding and transcription corepressor activity. An important paralog of this gene is KCTD15.

Less frequent clinical characteristics include nail dystrophy, dental anomalies, cutaneous syndactyly of the digits, and renal malformations. Penetrance appears to be high, although there is substantial variable expressivity within families. {ECO:0000269 PubMed:23541344}.
