Genetic Variant IRF6:p.Arg400Pro (chr1-209788625-C-G) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 4P and 4B. PM5PP2PP3BP4_Strong

The NM_006147.4(IRF6):c.1199G>C(p.Arg400Pro) variant causes a missense change involving the alteration of a conserved nucleotide. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R400Q) has been classified as Pathogenic.

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 0 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr1-209788626-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 3419.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

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 orofacial cleft 6, susceptibility to, van der Woude syndrome, autosomal dominant popliteal pterygium syndrome, tooth agenesis, van der Woude syndrome 1.

PP3

Multiple lines of computational evidence support a deleterious effect 9: AlphaMissense, BayesDel_addAF, BayesDel_noAF, Cadd, Eigen, MutationAssessor, PrimateAI, PROVEAN, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.009464204).
