Polymorphic Variants from UniProtKB/Swiss-Prot for CNDP1 Gene

The number of trinucleotide (CTG) repeat varies among different alleles leading to insertion of Leu residues in the signal peptide. The allele with 5 leucines (as shown in the reference entry) is known as the Mannheim allele. Diabetic patients with the CNDP1 Mannheim allele are less susceptible for nephropathy.
