Genes affected

ZEB2 (HGNC:14881): (zinc finger E-box binding homeobox 2) The protein encoded by this gene is a member of the Zfh1 family of 2-handed zinc finger/homeodomain proteins. It is located in the nucleus and functions as a DNA-binding transcriptional repressor that interacts with activated SMADs. Mutations in this gene are associated with Hirschsprung disease/Mowat-Wilson syndrome. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Jan 2010]

The ZEB2 p.Thr809Ala variant was not identified in the literature nor was it identified in ClinVar, Cosmic, MutDB or LOVD 3.0. The variant was identified in dbSNP (ID: rs1490526407) and in control databases in 3 of 251276 chromosomes at a frequency of 0.000012 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following population: European (non-Finnish) in 3 of 113640 chromosomes (freq: 0.000026), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other or South Asian populations. The c.2425A>G variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. The p.Thr809 residue is conserved in mammals, however four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM) do not suggest a high likelihood of impact to the protein. This information is not predictive enough to rule out pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
