Invitae RCV000695954 SCV000824495 likely pathogenic Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type a, 11 2018-04-13 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 6 of the B3GALNT2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is present in population databases (rs757347274, ExAC 0.009%). This variant has not been reported in the literature in individuals with B3GALNT2-related disease. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in B3GALNT2 are known to be pathogenic (PMID: 23453667). 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.
