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]

Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 01, 2024The c.14dupG variant, located in coding exon 1 of the FOXE3 gene, results from a duplication of G at nucleotide position 14, causing a translational frameshift with a predicted alternate stop codon (p.S5Rfs*280). This alteration is not expected to trigger nonsense-mediated mRNA decay and impacts greater than 50% of the protein. However, premature stop codons are typically deleterious in nature and a significant portion of the protein is affected (Ambry internal data). Although biallelic loss of function of FOXE3 has been associated with autosomal recessive FOXE3-related ocular development disorder, haploinsufficiency of FOXE3 has not been established as a mechanism of disease for autosomal dominant FOXE3-related ocular development disorder. Based on the supporting evidence, this variant is expected to be causative of autosomal recessive FOXE3-related ocular development disorder when present along with a second pathogenic variant on the other allele; however, its clinical significance for autosomal dominant FOXE3-related ocular development disorder is unclear. -
