Cysteamine cystinosis mechanism
WebJul 1, 2024 · Since cystinosis is a monogenic autosomal-recessive disease, patients normally have biallelic mutations in the CTNS gene (chromosome 17 p13.2), resulting in loss of functional cystinosin (also known as PQLC4) [ 81 ]. As a recessive disease, cystinosis incidence may be correlated with consanguinity. WebMost clinical data have been developed using cysteamine HCl or phosphocysteamine solutions. In all discussions that follow, administered amounts of various cysteamine salts will be expressed as amounts of cysteamine free base. Clinical Studies: There are approximately 200 pre-transplant cystinosis patients in the United States
