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]

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 78 of the FOXE3 protein (p.Ala78Thr). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with autosomal recessive FOXE3-related conditions (PMID: 29136273, 34046667). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 427852). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

The FOXE3 c.232G>A; p.Ala78Thr variant (rs377669670) is reported in both the homozygous and compound heterozygous states in individuals with FOXE3-related ocular disorders (Chesneau 2022, Plaisancie 2018, Reis 2021). This variant is also reported in ClinVar (Variation ID: 427852). It is observed in the general population with a low overall allele frequency of 0.004% (10/248542 alleles) in the Genome Aggregation Database. Computational analyses predict that this variant is deleterious (REVEL: 0.862). Based on available information, this variant is considered to be likely pathogenic for autosomal recessive anterior segment dysgenesis 2. It is uncertain whether or not this variant would cause susceptibility to familial thoracic aortic aneurysm 11. References: Chesneau B et al.

The c.232G>A (p.A78T) alteration is located in exon 1 (coding exon 1) of the FOXE3 gene. This alteration results from a G to A substitution at nucleotide position 232, causing the alanine (A) at amino acid position 78 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
