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]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-144398972-T-TGGAG is Pathogenic according to our data. Variant chr2-144398972-T-TGGAG is described in ClinVar as [Pathogenic]. Clinvar id is 448970.Status of the report is criteria_provided_single_submitter, 1 stars.
