Autosomal-Dominant Oligodontia and Identification of the WNT10B Mutation
(A) Front views and panoramic radiographs of dentitions of three affected individuals (II-1, III-1, and III-2 in C). Missing teeth are denoted by asterisks.
(B) Schematic analysis shows the positions of missing teeth in each of the affected individuals. Missing teeth are denoted by asterisks.
(C) The ZZYWL-2 pedigree. Filled circles and squares represent affected female and male family members, respectively. Subjects I-1, I-2, II-3, II-4, and II-5 were not available for clinical evaluation or DNA analysis. WES and Sanger sequencing were performed for five family members (II-1, II-2, III-1, III-2, and III-3).
(D) Representative Sanger chromatograms show the heterozygous missense mutation c.632G>A, resulting in the p.Arg211Gln substitution.
(E) All four mutations and the rare variant c.849C>A (p.Ile283Ile) detected in the present study affect the middle region (amino acids 190–284) of WNT10B.
