We show that oligodontia and predisposition to cancer are caused by a nonsense mutation, Arg656Stop, in the Wnt-signaling regulator AXIN2.

Considering the discrepancy between the high incidence rate of agenesis and the relatively small number of reported causative mutations in PAX9, MSX1 and AXIN2 genes, the genetic contribution to oligodontia probably is much more heterogeneous than expected so far.

Msx1, Pax9, and Axin2 are involved in non-syndromic hypodontia, while genes such as Shh, Pitx2, Irf6, and p63 are considered to participate in syndromic genetic disorders, which include tooth agenesis.

At present, the list of genes involved in human non-syndromic hypodontia includes not only those encoding a signaling molecule (TGFA) and transcription factors (MSX1 and PAX9) that play critical roles during early craniofacial development, but also genes coding for a protein involved in canonical Wnt signaling (AXIN2), and a transmembrane receptor of fibroblast growth factors (FGFR1).

Previous authors have described an unrelated family with autosomal dominant oligodontia and a variable colorectal phenotype segregating with a nonsense mutation of AXIN2, as well as a frameshift AXIN2 mutation in an unrelated individual with oligodontia.

Oligodontia as well as hypodontia (lack of one or more permanent teeth) are highly heritable conditions associated with mutations in the AXIN2, MSX1, PAX9, EDA, and EDAR genes.

To date, more than 300 genes have been found to be involved in tooth development, but only a few of these genes, such as MSX1, PAX9 and AXIN2, are related to the condition of non-syndromic oligodontia.

The findings suggest that the c.956+16A>G, c.1365A>G and c.1200+71A>G mutations of AXIN2 may be responsible for the oligodontia phenotype in this family, but these findings require further study.

We analysed this novel AXIN2 mutant, together with two reported AXIN2 mutants [c.1966C>T (p.Arg656Stop) and c.1994delG (p.Leu688Stop)] that cause colorectal cancer with and without oligodontia, to study the effect of the mutant p.His660Tyr on the Wnt/β-catenin signaling pathway and to compare the molecular pathogenesis of different AXIN2 mutants in tooth agenesis and carcinogenesis.

In this case report we describe a family with c.1972delA, p.Ser658Alafs*31 nonsense variant in AXIN2 where the three confirmed carriers presented with both oligodontia and colorectal adenomatous polyposis; mean number of teeth missing in carriers was 16.5 (range 11-22) and mean number of polyps in carriers was 49 (range 5->100, polyps were predominantly adenomatous).
