Genes affected

ZNF674 (HGNC:17625): (zinc finger protein 674) This gene encodes a zinc finger protein with an N-terminal Kruppel-associated box-containing (KRAB) domain and 11 Kruppel-type C2H2 zinc finger domains. Like other zinc finger proteins, this gene may function as a transcription factor. This gene resides on an area of chromosome X that has been implicated in nonsyndromic X-linked cognitive disabilities. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2017]
