Labcorp Genetics (formerly Invitae), Labcorp RCV003602221 SCV004434788 likely pathogenic Autosomal recessive severe congenital neutropenia due to G6PC3 deficiency 2023-02-18 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with G6PC3-related conditions. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 3 of the G6PC3 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 G6PC3 are known to be pathogenic (PMID: 19118303, 25491320).
