Comparative and genetic analysis of the porcine glucocerebrosidase (GBA) gene.

The genomic sequence of the porcine (Sus scrofa) glucocerebrosidase (GBA) gene (approximately 5.7 kb), encoding glucocerebrosidase (glucosylceramidase; acid beta-glucosidase; EC 3.2.1.45), was determined and compared with human (Homo sapiens) GBA and GBAP (pseudogene). The porcine gene harbours 11 exons and 10 introns, and the genomic organization is identical with human GBA. The exon sequences, coding for signal peptide and mature protein, show 81% and 90% sequence identity, respectively, with the corresponding human GBA sequences. Short interspersed elements, SINEs (PREs), are present in introns 2, 4 and 7. There is no evidence of a pseudogene in pig. The deduced protein sequence of GBA consists of 39 amino acids of signal peptide (long form) and 497 amino acids of the mature protein; the latter shows 90% sequence identity with the human protein. Four polymorphisms were observed within the porcine gene: insertion/deletion of one of the two SINEs (PREs) in intron 2 (locus PREA); deletion of a 37- to 39-bp stretch in intron 4 (one direct repeat and 5' end of PRE); deletion of a 47-bp stretch in the middle part of PRE in intron 4 (locus PREB); and single-base transition (C-T) in intron 6 (locus HaeIII-RFLP). GBA was assigned to chromosome 4q21 by FISH and was localized to the same region by linkage analysis and RH mapping, i.e., to the chromosome 4 segment where quantitative trait loci for growth and some carcass traits are located.[1]
