A Custom-Made Newborn Screening Test for Wilson's Disease in Puerto Rico.

ABSTRACT: Background Wilson's disease (WD) is an autosomal recessive progressive, disabling, life-threatening disease. Although early diagnosis and treatment can halt disease progression and reverse disability, diagnosis is often challenging, with a mean diagnostic delay of approximately two years. At least 98% of WD-causing variants are in the ATPase copper transporting beta (ATP7B) gene. Identifying ATP7B mutations that cause WD in Puerto Rico will allow newborn screening for WD, as well as preventive, life-saving treatment. Methodology TaqMan genotyping assays were performed on 174 random volunteers in southwestern Puerto Rico and on three independent WD cases for rs367956522 and rs140708492, single-nucleotide polymorphisms (SNPs) composing a WD-causing haplotype.
