Invitae | RCV000870799 | SCV001012342 | uncertain significance | Myofibrillar myopathy 4 | 2024-01-16 | criteria provided, single submitter | clinical testing | The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1:c.321+1361C>A in the primary transcript. This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 135 of the LDB3 protein (p.Thr135Asn). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with LDB3-related conditions. ClinVar contains an entry for this variant (Variation ID: 702008). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. |

Ambry Genetics | RCV002320017 | SCV002630148 | uncertain significance | Cardiovascular phenotype | 2023-12-09 | criteria provided, single submitter | clinical testing | The c.404C>A (p.T135N) alteration is located in exon 4 (coding exon 4) of the LDB3 gene. This alteration results from a C to A substitution at nucleotide position 404, causing the threonine (T) at amino acid position 135 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
