Invitae | RCV000807342 | SCV000947390 | pathogenic | not provided | 2024-01-04 | criteria provided, single submitter | clinical testing | This sequence change affects a splice site in intron 6 of the HOGA1 gene. RNA analysis indicates that disruption of this splice site induces altered splicing and likely disrupts the C-terminus of the protein. Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. Disruption of this splice site has been observed in individuals with primary hyperoxaluria type 3 (PMID: 25972204, 26340091). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 625169). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that disruption of this splice site results in skipping of exon 6 and introduces a new termination codon (PMID: 26340091). However the mRNA is not expected to undergo nonsense-mediated decay. For these reasons, this variant has been classified as Pathogenic. |
