Invitae | RCV001928617 | SCV002193334 | uncertain significance | Myofibrillar myopathy 4 | 2022-08-15 | criteria provided, single submitter | clinical testing | 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with LDB3-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 433 of the LDB3 protein (p.Pro433Leu). The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1:c.*17019C>T in the primary transcript. |
Ambry Genetics | RCV003167170 | SCV003860824 | uncertain significance | Cardiovascular phenotype | 2023-02-23 | criteria provided, single submitter | clinical testing | The p.P433L variant (also known as c.1298C>T), located in coding exon 9 of the LDB3 gene, results from a C to T substitution at nucleotide position 1298. The proline at codon 433 is replaced by leucine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
