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]

p.Ile331X (c.990_9901del) in exon 6 of ZNF674: This variant is not expected to h ave clinical significance because it has been identified in 0.4% (26/6239) of Eu ropean chromosomes by the NHLBI Exome Sequence Project (http://evs.gs.washington .edu/EVS). This variant is predicted to cause a frameshift, which alters the pro tein?s amino acid sequence beginning at position 331 and leads to an immediate p remature termination codon. This alteration occurs within the last exon and is m ore likely to escape nonsense mediated decay (NMD) and result in a truncated pro tein. -
