Mutations in the gene for 3′-phospho-adenosine-5′-phosphosulfate synthase 2 (PAPSS2) are linked to bone and cartilage mal-formation. More recently, we could identify PAPSS2-mutations as mono-genetic cause for androgen excess in women due to apparent SULT2A1 deficiency, the enzyme responsible for sulfation of the testosterone precursor DHEA that relies on PAPS provision by PAPS synthases. The only human orthologue, PAPSS1, is expressed in the affected tissu...
