In<unk> , the diagnosis of homozygotes is difficult, requiring a genomic DNA screening with allele-specific probes or an enzyme assay from a liver biopsy. Once identified, parents of infants who carry mutant aldolase B alleles leading to<unk> , or older individuals who have clinical histories compatible with<unk>  can be identified and counselled with regard to preventive therapy: dietary exclusion of foods containing<unk> , sucrose, or sorbitol.
