Invitae | RCV000729603 | SCV004695713 | uncertain significance | not provided | 2024-01-26 | criteria provided, single submitter | clinical testing | This sequence change affects codon 737 of the ABCB4 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ABCB4 protein. This variant also falls at the last nucleotide of exon 17, which is part of the consensus splice site for this exon. This variant is present in population databases (rs763404399, gnomAD 0.004%). This variant has been observed in individual(s) with ABCB4-related conditions (PMID: 33390354). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 594341). 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 may disrupt the consensus splice site. 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. |
