Pseudoxanthoma elasticum is an autosomal recessive heritable disorder caused by mutations in ABCC6. We describe two siblings showing typical skin lesions and a clinical diagnosis of pseudoxanthoma elasticum. Genetic analysis of ABCC6 revealed a novel homozygous c.4041G > A variant located in the last position of exon 28 that compromises the splicing donor site, resulting in a shorter messenger RNA. The deletion impairs the nucleotide-binding fold region, which is crucial for ABCC6 function.
