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 made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), IRF6. . Gene score misZ 2.7435 (greater than the threshold 3.09). Trascript score misZ 3.8897 (greater than threshold 3.09). GenCC has associacion of gene with orofacial cleft 6, susceptibility to, van der Woude syndrome, autosomal dominant popliteal pterygium syndrome, tooth agenesis, van der Woude syndrome 1.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.895
