Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2
The NM_001174096.2(ZEB1):c.170C>T(p.Pro57Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000874 in 1,613,330 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★).
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]
Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.170C>T (p.P57L) alteration is located in exon 2 (coding exon 2) of the ZEB1 gene. This alteration results from a C to T substitution at nucleotide position 170, causing the proline (P) at amino acid position 57 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
