Variant summary
Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1PP3PP5_Very_Strong
The NM_012186.3(FOXE3):c.232G>A(p.Ala78Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000451 in 1,574,228 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. A78A) has been classified as Likely benign.

This variant is associated with the following publications: (PMID: 34046667, 30187164, 29314435, 34426522, 31589614, 35170016, 29136273) -
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.

Congenital primary aphakia;C1862839:Anterior segment dysgenesis Pathogenic:1
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, 35170016). 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). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt FOXE3 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
Cardiovascular phenotype Uncertain:1
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. -
