Assignment of two human α-1,3-galactosyltransferase gene sequences (GGTA1 and GGTA1P) to chromosomes 9q33–q34 and 12q14–q15
Abstract
alpha-1,3-Galactosyltransferase is a terminal glycosyltransferase that is widely expressed in a variety of mammalian species, with the notable exception of man, apes, and Old World monkeys. Although transcripts for this enzyme are not detectable in humans, homologous sequences have been identified in human genomic DNA. These sequences correspond to a processed pseudogene that maps to chromosome 12 and the inactivated remnant of the once functional source gene that maps to chromosome 9. We have now established that the former sequence (GGTA1P) is localized to 12q14-q15 and the latter sequence (GGTA1) is localized to 9q33-q34 [corrected].

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
