GeneDx RCV000606491 SCV000715726 likely benign not specified 2017-02-06 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Invitae RCV000651514 SCV000773366 uncertain significance Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A13 2022-07-12 criteria provided, single submitter clinical testing This sequence change falls in intron 1 of the B4GAT1 gene. It does not directly change the encoded amino acid sequence of the B4GAT1 protein. It affects a nucleotide within the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with B4GAT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 507234). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
