Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM2 PP2 PP3_Moderate

The NM_001453.3(FOXC1):​c.38T>G​(p.Leu13Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000268 in 1,493,636 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 Uncertain significance (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L13V) has been classified as Uncertain significance.

Genes affected

FOXC1 (HGNC:3800): (forkhead box C1) This gene belongs to the forkhead family of transcription factors which is characterized by a distinct DNA-binding forkhead domain. The specific function of this gene has not yet been determined; however, it has been shown to play a role in the regulation of embryonic and ocular development. Mutations in this gene cause various glaucoma phenotypes including primary congenital glaucoma, autosomal dominant iridogoniodysgenesis anomaly, and Axenfeld-Rieger anomaly.

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 31 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Trascript score misZ: -3.6526 (below the threshold of 3.09). GenCC associations: The gene is linked to Rieger anomaly, Axenfeld-Rieger syndrome type 3, anterior segment dysgenesis 3, isolated aniridia, Axenfeld-Rieger syndrome, Axenfeld anomaly, aniridia, Peters anomaly.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.863
