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

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PM1

In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 10 uncertain in NM_006147.4

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=0.36167914).

BS2

High AC in GnomAdExome4 at 6 AD,Unknown gene.
