Ambry Genetics RCV000622255 SCV000735402 uncertain significance Cardiovascular phenotype 2020-01-15 criteria provided, single submitter clinical testing The p.R265H variant (also known as c.794G>A), located in coding exon 5 of the LDB3 gene, results from a G to A substitution at nucleotide position 794. The arginine at codon 265 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species; however, histidine is the reference amino acid in other vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.

Loeys Lab,Universiteit Antwerpen RCV001375640 SCV001572565 uncertain significance Primary dilated cardiomyopathy 2021-02-26 criteria provided, single submitter clinical testing This sequence change results in a missense variant in the LDB3 gene (p.(Arg333His)). This variant is present in population databases with a prevalence of 36/282804 in GnomAD (BS1) . This variant has not been reported in the literature and no functional data are available. Prediction programs show conflicting results (Align GVGD: C0; Polyphen-2-HumDiv: possibly damaging ; Polyphen-2-HumVar: benign; SIFT: tolerated; MutationTaster: disease causing). The variant affects a highly conserved nucleotide and a moderately conserved amino acid. We identified this variant in a patients with DCM. In conclusion this variant was classified as a variant of unknown significance according to ACMG-guidelines (insufficient data, criteria for other classification are not met: BS1).
