Description

This variant has not been reported in the literature in individuals affected with LAMA4-related conditions. 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. 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. This variant is not present in population databases (gnomAD no frequency). This variant results in the deletion of part of exon 39 (c.5306-8_5326del) of the LAMA4 gene. It affects a nucleotide within the consensus splice site.
