This sequence change creates a premature translational stop signal (p.Leu289Phefs*10) in the ALDOB gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ALDOB are known to be pathogenic (PMID: 18541450). This premature translational stop signal has been observed in individuals with hereditary fructose intolerance (PMID: 1967768, 15880727). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 218381). This variant is also known as L288delC.

The variant allele was found at a frequency of 4e-06 in 251092 control chromosomes (gnomAD). The variant, c.865delC (also known as L288delC), has been reported in the literature in homozygous or compound heterozygous state in multiple individuals affected with Hereditary Fructose Intolerance (Cross_1990, Santer_2005, Esposito_2010, DiDato_2019). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three submitters have provided clinical-significance assessments for this variant in ClinVar after 2014, and all of them classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
