RCV001309486 | SCV001498986 | uncertain significance | Cutis laxa, autosomal recessive, type 1B | 2021-09-09 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This sequence change replaces arginine with histidine at codon 176 of the EFEMP2 protein (p.Arg176His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs772504760, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with EFEMP2-related conditions. 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 | RCV003166769 | SCV003860506 | uncertain significance | Cardiovascular phenotype | 2022-11-04 | criteria provided, single submitter | clinical testing | The p.R176H variant (also known as c.527G>A), located in coding exon 5 of the EFEMP2 gene, results from a G to A substitution at nucleotide position 527. The arginine at codon 176 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
