Commentary on Variants in the ABCC6 Gene Implicated in Pseudoxanthoma Elasticum, a Heritable Ectopic Mineralization Disorder

Significant progress has been made in understanding pseudoxanthoma elasticum (PXE), which results from mutations in ABCC6. The low prevalence of PXE and its heterotypic presentation confound genotype-phenotype correlations and the characterization of many identified variants. Kowal et al. (2022) present an in vivo model to characterize and annotate ABCC6 variants, establishing a novel system for allele annotation in the patient population.
