0 Chromosome 2 & 3



CHROMOSOME 2 :
  • HNPCC (MSH 2)
  • Cysteinuria

CHROMOSOME 3 :
  • HNPCC (MLH 1) 
  • VHL
  • Alkaptonuria


The majority of HNPCC ( hereditary non-polyposis colorectal cancer ) is caused by mutations in one of several mismatch-repair genes:
MSH2, MSH6, and PMS1 on chromosome 2, 
MLH1 on chromosome 3, 
MSH3 on chromosome 5, and 
PMS2 on chromosome 7. 

MSH2 and MLH1 account for the majority of mutations in HNPCC families.
