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

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.20931262).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000138 (21/152266) while in subpopulation AFR AF= 0.000505 (21/41550). AF 95% confidence interval is 0.000338. There are 0 homozygotes in gnomad4. There are 12 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd at 20 AD gene.

The c.464G>T (p.S155I) alteration is located in exon 4 (coding exon 4) of the ZEB1 gene. This alteration results from a G to T substitution at nucleotide position 464, causing the serine (S) at amino acid position 155 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
