Invitae RCV000235483 SCV001396576 pathogenic Propionic acidemia 2023-11-27 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 1 of the PCCA gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in PCCA are known to be pathogenic (PMID: 15464417). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. Disruption of this splice site has been observed in individual(s) with propionic acidemia (PMID: 27227689, 35331292). ClinVar contains an entry for this variant (Variation ID: 218251). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
