• FOXE3 p.Arg104Gly

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM1 PM5

The NM_012186.3(FOXE3):​c.310_312delCGCinsGGG​(p.Arg104Gly) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R104C) has been classified as Likely pathogenic.

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]

LINC01389 (HGNC:50661): (long intergenic non-protein coding RNA 1389)

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM1: In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 11 uncertain in NM_012186.3
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr1-47416625-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 427853.
