Invitae RCV001214626 SCV001386314 pathogenic Mucopolysaccharidosis, MPS-IV-A 2023-09-21 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 944266). This sequence change affects an acceptor splice site in intron 8 of the GALNS 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 GALNS are known to be pathogenic (PMID: 12442278). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with MPS IVA (PMID: 24120057; Invitae). 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.
