Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 3P and 2B. PM2 PP2 BP4 BP6

The NM_006147.4(IRF6):​c.1173G>T​(p.Leu391Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (no stars). Synonymous variant affecting the same amino acid position (i.e. L391L) has been classified as Likely benign.

Genes affected

IRF6 (HGNC:6121): (interferon regulatory factor 6) This gene encodes a member of the interferon regulatory transcription factor (IRF) family. Family members share a highly-conserved N-terminal helix-turn-helix DNA-binding domain and a less conserved C-terminal protein-binding domain. The encoded protein may be a transcriptional activator. Mutations in this gene can cause van der Woude syndrome and popliteal pterygium syndrome. Mutations in this gene are also associated with non-syndromic orofacial cleft type 6. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the IRF6 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 45 curated pathogenic missense variants (we use a threshold of 10). The gene has 10 curated benign missense variants. Gene score misZ: 2.7435 (below the threshold of 3.09). Trascript score misZ: 3.8897 (above the threshold of 3.09). GenCC associations: The gene is linked to van der Woude syndrome 1, van der Woude syndrome, autosomal dominant popliteal pterygium syndrome, orofacial cleft 6, susceptibility to, tooth agenesis, IRF6-related condition, popliteal pterygium syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.41841626).
• BP6: Variant 1-209789673-C-A is Benign according to our data. Variant chr1-209789673-C-A is described in ClinVar as Benign. ClinVar VariationId is 559495.Status of the report is no_assertion_criteria_provided, 0 stars.
