Invitae RCV000031955 SCV000944588 likely pathogenic Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome 2023-12-02 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg275*) in the SLC25A15 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 27 amino acid(s) of the SLC25A15 protein. This variant is present in population databases (rs202247807, gnomAD 0.006%). This premature translational stop signal has been observed in individuals with hyperornithinemia-hyperammonemia-homocitrullinuria syndrome (PMID: 16376511, 23430880). ClinVar contains an entry for this variant (Variation ID: 38403). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant disrupts the C-terminus of the SLC25A15 protein. Other variant(s) that disrupt this region (p.Glu288Glyfs*3) have been observed in individuals with SLC25A15-related conditions (PMID: 11552031, 12807890). This suggests that this may be a clinically significant region of the protein. 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.
