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 Benign. Variant got -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BP6: Variant 2-144396506-G-A is Benign according to our data. Variant chr2-144396506-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 137954.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-144396506-G-A is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=2.61 with no splicing effect.
• BS2: High AC in GnomAd at 9 AD gene.

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
