The present study investigated a family with SHFM and hypodontia; determined the sequences of DLX5, WNT8B, WNT10B, BHLHA9, CDH3, DYNC1I1 and FGFR1; and performed single nucleotide polymorphism-array analysis.
These findings suggest that tooth hypodontia in patients with hyperbilirubinemia might be due to bilirubin-induced cell death and dentinogenic dysfunction of odontogenic stem cells via AKT, ERK1/2, and NF-κB pathways and also suggested that bilirubin-induced impairments in odontogenic stem cells were reversible when bilirubin stimulation is interrupted.
The previously described, functional GREM2 mutation (c.226C > G, p.Gln76Glu) was identified in two patients with hypodontia and associated dental anomalies, including taurodontism and microdontia.
Enamel-renal-gingival syndrome (ERGS; OMIM #204690), a rare autosomal recessive disorder caused by mutations in FAM20A, is characterized by nephrocalcinosis, nephrolithiasis, amelogenesis imperfecta, hypoplastic type, gingival fibromatosis and other dental abnormalities, including hypodontia and unerupted teeth with large dental follicles.
To report the dento-craniofacial phenotype of a family affected by a WNT10A HED and to describe the implant-based oral rehabilitation of a patient presenting a severe oligodontia linked to this mutation.

This is the second report describing SMOC2 mutations with oligodontia and microdontia underlining the key role for this signalling molecule in tooth development.
To further confirm this observation, in this study, we employed 89 individuals diagnosed with sporadic non-syndromic oligodontia (40 males and 49 females) to investigate the relationship between polymorphism in rs929387 of GLI3 and tooth agenesis.
Cleft-side MxI2 agenesis in CLP subjects appears to be largely a genetically controlled anomaly associated with cleft development, rather than a collateral environmental consequence of the adjacent cleft defect, since increased hypodontia involving multiple missing teeth observed remote from a cleft clearly has a significant genetic basis.
Moreover, the gene-gene interaction analysis revealed a significant epistatic interaction between CHDH (rs6445606) and PLD2 (rs3764897) in the susceptibility to hypodontia (p=0.004).

The aim of this study was to characterize Swedish families with non-syndromic cleft lip and/or palate (NSCL/P) for mutations or other sequence variants in the interferon regulatory factor 6 (IRF6) gene, as well as to describe their cleft phenotypes and hypodontia.
Here we report the exclusion of EGF, EGFR, and FGF-3 loci as possible sites for gene mutation causing incisor-premolar hypodontia in our family material.
