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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.427 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
PP5
Variant 6-1611397-CG-C is Pathogenic according to our data. Variant chr6-1611397-CG-C is described in ClinVar as [Pathogenic]. Clinvar id is 537391.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High AC in GnomAdExome4 at 8 AD gene.

Submissions by phenotype

Axenfeld-Rieger syndrome type 3 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 19, 2023This sequence change creates a premature translational stop signal (p.Ser320Argfs*81) in the FOXC1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 234 amino acid(s) of the FOXC1 protein. 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 premature translational stop signal has been observed in individual(s) with Axenfeld-Rieger syndrome (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 537391). For these reasons, this variant has been classified as Pathogenic. -
