placental HTRA1 is significantly up-regulated in preeclampsia (PE) (significantly increased in early-onset PE, but significantly reduced in late-onset PE)
Susceptibility to age-macular dgeneration (AMD)
Variant & Polymorphism SNP , other
  • in the promoter region is a major genetic risk factor for wet AMD
  • polymorphism, rs11200638, is a strong candidate with a functional consequence that predisposes Japanese to develop neovascular AMD
  • HTRA1 expression is enhanced by AMD specific indel mutation in the promoter region of HTRA1 gene, and this enhanced HTRA1 may be concerned with induce retinal neovascularization , and AMD-associated silent polymorphisms in HTRA1 impair its ability to antagonize IGF1
    • Candidate gene
    Marker
  • significant increase of serum HTRA1 in early-onset PE suggests that it may be a potential biomarker for the diagnosis of early-onset preeclampsia (PE) at disease presentation
