Genes affected

GRHPR (HGNC:4570): (glyoxylate and hydroxypyruvate reductase) This gene encodes an enzyme with hydroxypyruvate reductase, glyoxylate reductase, and D-glycerate dehydrogenase enzymatic activities. The enzyme has widespread tissue expression and has a role in metabolism. Type II hyperoxaluria is caused by mutations in this gene. [provided by RefSeq, Jul 2008]

This sequence change falls in intron 4 of the GRHPR gene. It does not directly change the encoded amino acid sequence of the GRHPR protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs757796926, gnomAD 0.0009%). This variant has been observed in individuals with primary hyperoxaluria type II (PMID: 25644115, 28893421). ClinVar contains an entry for this variant (Variation ID: 548673). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
