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). This variant has not been reported in the literature in individuals affected with LDB3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 559 of the LDB3 protein (p.Arg559Leu). This variant also falls at the last nucleotide of exon 10, which is part of the consensus splice site for this exon. The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1:c.*17397G>T in the primary transcript. |
