Labcorp Genetics (formerly Invitae), Labcorp RCV000670419 SCV004479504 likely pathogenic Deficiency of galactokinase 2023-08-24 criteria provided, single submitter clinical testing 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. ClinVar contains an entry for this variant (Variation ID: 554737). This variant has not been reported in the literature in individuals affected with GALK1-related conditions. 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. This sequence change affects a donor splice site in intron 6 of the GALK1 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 GALK1 are known to be pathogenic (PMID: 7670469, 10790206).
