    REGULATION

    ASSOCIATED DISORDERS
    corresponding disease(s)
    Susceptibility to diabetic nephropathy, may at least be mediated by altered glucose metabolism in type 2 diabetic patients (Sauerhöfer 2007)
    Variant & Polymorphism repeat
  • trinucleotide repeat in exon 2, coding for a leucine repeat in the leader peptide of the carnosinase-1 precursor, was associated with diabetic nephropathy
  • diabetic patients with the Mannheim allele (5 Leucines) are less susceptible to nephropathy (Janssen 2005)
    • Candidate gene
  • deficiency of CNDP1 may cause homocarcinosis
  • association between the CNDP1 gene and diabetic nephropathy is ex specific (Mooyaart 2010)
    • Marker
    Therapy target
  • CNDP1 secretion is significantly higher in cells expressing variants with more than 5 leucines in the signal peptide, it might explain why patients with homozygous 5L allele have low serum carnosinase activity and are protected against diabetic nephropathy (Riedl 2007)
