Genes affected

FOXE3 (HGNC:3808): (forkhead box E3) This intronless gene belongs to the forkhead family of transcription factors, which is characterized by a distinct forkhead domain. The protein encoded functions as a lens-specific transcription factor and plays an important role in vertebrate lens formation. Mutations in this gene are associated with anterior segment mesenchymal dysgenesis and congenital primary aphakia. [provided by RefSeq, Dec 2009]

Pathogenic, no assertion criteria provided	research	Human Developmental Genetics Laboratory, Medical College of Wisconsin	May 01, 2021	- -
Pathogenic, criteria provided, single submitter	clinical testing	3billion	Jan 03, 2022	Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through protein truncation. The predicted truncated protein may be shortened by more than 10% (PVS1_S). The variant has been reported to be associated with FOXE3 related disorder (ClinVar ID: VCV000008448).The variant was co-segregated with Anterior segment dysgenesis 2, multiple subtypes in multiple affected family members (PMID: 16826526, 32499604, 20361012) (PP1_S). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000162, PM2_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

Pathogenic, criteria provided, single submitter	clinical testing	Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	Sep 02, 2022	Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with anterior segment dysgenesis 2, multiple subtypes (MIM#610256). (I) 0108 - This gene is associated with both recessive and dominant disease. This gene is associated with autosomal recessive anterior segment dysgenesis 2, multiple subtypes (MIM#610256) and there are also many reports of a less severe autosomal dominant eye phenotype involving Peter's anomaly and other ocular dysgenesis (PMIDs: 16826526, 20361012, OMIM). Autosomal dominant aortic aneurysm, familial thoracic 11 (MIM#617349) has also been reported in several families but this association is currently uncertain (PMID: 20301299, OMIM). (I) 0205 - Variant is predicted to result in a truncated protein (premature termination codon is NOT located at least 54 nucleotides upstream of the final exon-exon junction) with less than 1/3 of the protein sequence affected. (SP) 0252 - This variant is homozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 for a recessive condition (7 heterozygotes, 0 homozygotes). (SP) 0704 - Another downstream truncating variant comparable to the one identified in this case has limited previous evidence for pathogenicity (DECIPHER). (SP) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been classified as pathogenic by several clinical laboratories in ClinVar and observed as homozygous in at least four families with anterior segment dysgenesis or primary aphakia (PMIDs: 27218149, 16826526, 32499604, 20361012). (SP) 0901 - This variant has strong evidence for segregation with disease. This variant has been seen to segregate in several large families in a homozygous state (PMIDs: 27218149, 16826526, 20361012). (SP) 1002 - This variant has moderate functional evidence supporting abnormal protein function. This variant has been show to disrupt the binding of FOXE3 with DNAJB1 leading to reduced expression of the latter (PMID: 27218149). (SP) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -

Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Mar 16, 2021	Published functional studies demonstrate that C240X variant leads to a decrease in the expression of downstream target gene expression (Khan et al., 2016); Nonsense variant in the C-terminus predicted to result in protein truncation, as the last 80 amino acids are lost, and other loss-of-function variants have been reported downstream in the Human Gene Mutation Database (Stenson et al., 2014); This variant is associated with the following publications: (PMID: 20361012, 16826526, 20140963, 24033328, 27218149, 32499604) -
