ALDH1A2 and isolated congenital adermatoglyphia: Three SNPs located in two genes were identified as being associated with ADG; one of these genes was ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 5 (ST6GALNAC5) on BTA3, while the other gene was aldehyde dehydrogenase 1 family member A2 (ALDH1A2) on BTA10.
