Genes affected

ZEB1 (HGNC:11642): (zinc finger E-box binding homeobox 1) This gene encodes a zinc finger transcription factor. The encoded protein likely plays a role in transcriptional repression of interleukin 2. Mutations in this gene have been associated with posterior polymorphous corneal dystrophy-3 and late-onset Fuchs endothelial corneal dystrophy. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Mar 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 10-31510691-CA-C is Pathogenic according to our data. Variant chr10-31510691-CA-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1032236.Status of the report is criteria_provided_single_submitter, 1 stars.
