Abstract
Phenotypic characteristics expressed in syndromes give clues to the factors involved in the cause of isolated forms of the same defects. We investigated two genes responsible for craniofacial syndromes,
FGFR1
and
IRF6
, in a collection of families with isolated tooth agenesis. Cheek swab samples were obtained for DNA analysis from 116 case/parent trios. Probands had at least one developmentally missing tooth, excluding third molars. In addition, we studied 89 cases and 50 controls from Ohio to replicate any positive findings. Genotyping was performed by kinetic polymerase chain-reaction or TaqMan assays. Linkage disequilibrium analysis and transmission distortion of the marker alleles were performed. The same variants in the
IRF6
gene that are associated with isolated orofacial clefts are also associated with human tooth agenesis (rs861019,
P
= 0.058; rs17015215—V274I,
P
= 0.0006; rs7802,
P
= 0.004). Mutations in
IRF6
cause Van der Woude and popliteal pterygium syndromes. The craniofacial phenotypic characteristics of these syndromes include oral clefts and preferential tooth agenesis of incisors and premolars, besides pits on the lower lips. Also it appears that preferential premolar agenesis is associated with
FGFR1
(
P
= 0.014) and
IRF6
(
P
= 0.002) markers. There were statistically significant data suggesting that
IRF6
interacts not only with
MSX1
(
P
= 0.001), but also with
TGFA
(
P
= 0.03).
