In the group that combined individuals affected by isolated cleft lip and palate, tooth agenesis, supernumerary teeth, molar incisor hypomineralization, or dental caries, we found an association with rs622260 but not with the rs10798049 marker. We determined that the allele C of rs622260 was overrepresented in all individuals studied compared with a group of unrelated individuals who did not present any of

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
