RCV001857037 | SCV002194505 | pathogenic | not provided | 2025-01-06 | criteria provided, single submitter | clinical testing | This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 568 of the ABCC6 protein (p.Phe568Ser). This variant is present in population databases (rs66864704, gnomAD 0.07%). This missense change has been observed in individual(s) with clinical features of pseudoxanthoma elasticum (PMID: 16410789; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 433241). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ABCC6 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. |

RCV000499069 | SCV004171974 | likely pathogenic | Autosomal recessive inherited pseudoxanthoma elasticum | 2023-01-24 | criteria provided, single submitter | clinical testing | The missense c.1703T>C (p.Phe568Ser) variant in ABCC6 gene has been reported previously in multiple individuals affected with pseudoxanthoma elasticum (Ringpfeil et al. 2006; Legrand et al. 2017; Verschuere et al. 2021). The p.Phe568Ser variant is reported with an allele frequency of 0.001% in the gnomAD exomes database and is novel (not in any individuals) in 1000 Genomes database. This variant has been reported to the ClinVar database as Uncertain Significance / Pathogenic. The amino acid change p.Phe568Ser in ABCC6 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Phe at position 568 is changed to a Ser changing protein sequence and it might alter its composition and physico-chemical properties. Additional studies will be required to prove the pathogenicity of this variant. For these reasons, this variant has been classified as Likely Pathogenic. |
