ALDOB

ALDOB

A gene on chromosome 9q21.3-q22.2 that encodes aldolase B (fructose-bisphosphate aldolase), a glycolytic enzyme that catalyses the reversible conversion of fructose-1,6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. It is expressed in the developing embryo and in adult muscle, adult liver, kidney and intestine.

Molecular pathology
ALDOB mutations cause hereditary fructose intolerance.

In the hepatocarcinogenesis of NAFLD&NASH in Figure 2, we also identified eight genes with differences in expression between NAFLD&NASH and HCC, i.e., HIST2H2BE (p value [less than or equal to] 1.00 x [10.sup.-3]), RFC5 (p value < 1.00 x [10.sup.-3]), HSPB1 (p value [less than or equal to] 1.00 x [10.sup.-3]), ZNF480 (p value [less than or equal to] 1.00 x [10.sup.-3]), TUBA1C (p value [less than or equal to] 1.00 x [10.sup.-3]), RPL30 (p value [less than or equal to] 1.00 x [10.sup.-3]), FRAT2 (p value [less than or equal to] 1.00 x [10.sup.-3]), and ALDOB (p value [less than or equal to] 1.5 x [10.sup.-2]).
In addition, the dysregulation of TUBA1C caused by abnormal miR-122 silencing and the dysregulation of ALDOB caused by both hypermethylation and abnormal miR-21 silencing might facilitate tumor metastasis.
In addition, we also found nine genes that play a central role in the upper progression path of Figure 1(a), i.e., two DNA repair-related genes (histone cluster 2 (H2be; HIST2H2BE) and replication factor C5 (RFC5)), four apoptosis-related genes (heat shock 27-kDa protein 1 (HSPB1), zinc finger protein 480 (ZNF480), tubulin alpha 1c (TUBA1C), and ribosomal protein L30 (RPL30)), and three metabolism-related genes (aldolase B (ALDOB), frequently rearranged in advanced T-cell lymphomas 2 (FRAT2), and tRNA methyltransferase 1 (TRMT1)).
In the analysis of the GSE12817 dataset, important genes such as Adm, Aldob, Pkm2, Crem, and nod3l were identified.
Aldob, Txnip, Crem, Adm, and Fos were found among the 16 most upregulated genes known to be strongly induced by high glucose.
These changes--often indicative of fructose intolerance--were correlated to a damaging mutation in ALDOB (aldolase, fructose-bisphosphate B), which encodes the fructose-bisphosphate aldolase in the sorbitol degradation pathway.

Direct sequencing of exons 5 and 9 of the ALDOB gene (aldolase B, fructose-bisphosphate) (2) confirmed HFI due to a homozygous G>C transition in exon 5.
Mutations in the ALDOB gene on chromosome 9822.3 have been identified as the genetic cause of the disease.
We recommend that the laboratory instead perform genetic testing for HFI, which leads to a definitive diagnosis in most cases, because only 3 missense mutations in the ALDOB gene account for 85%-95% of the HFI alleles in different Caucasian populations (A149P, A174D, and N334K) (9, 10).
