RCV000038755 | SCV000062433 | uncertain significance | not specified | 2012-01-05 | criteria provided, single submitter | clinical testing | Variant classified as Uncertain Significance - Favor Benign. The Gly115Ser varia nt (LDB3) has been identified in 1 individual with DCM out of >500 Caucasian pro bands (>1000 chromosomes) and was absent from 368 Caucasian and 372 Black contro l chromosomes tested by our laboratory. Glycine (Gly) at position 115 is not con served in mammals and several other mammals have a serine (Ser) at this position , increasing the likelihood that a change may be tolerated. Computational tools are mixed in the prediction of the pathogenicity of this variant (AlignGVGD & SI FT = benign, PolyPhen2 = pathogenic), though the accuracy of these tools is unkn own. Additional information is needed to fully assess the clinical significance of the Gly115Ser variant. |

Ambry Genetics | RCV003162340 | SCV003859914 | uncertain significance | Cardiovascular phenotype | 2022-11-04 | criteria provided, single submitter | clinical testing | The p.G115S variant (also known as c.343G>A), located in coding exon 4 of the LDB3 gene, results from a G to A substitution at nucleotide position 343. The glycine at codon 115 is replaced by serine, an amino acid with similar properties. This alteration has been reported in a dilated cardiomyopathy cohort and a limb girdle muscular dystrophy cohort (Aurino S et al. Acta Myol, 2008 Dec;27:90-7; Pugh TJ et al. Genet Med, 2014 Aug;16:601-8). This amino acid position is well conserved in available vertebrate species. 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. |
