Genetics have been implicated to affect susceptibility to diabetic nephropathy. Genomewide<br />

association study was carried out to elucidate and identify possible genetic markers<br />

for diabetes nephropathy in Malay Type 2 Diabetes Mellitus patients. DNA samples from<br />

84 subjects with normoalbuminuria, 51 subjects with microalbuminuria, 34 subjects with<br />

macroalbuminuria and 27 subjects with ESRD were genotyped on the Affymetrix 100K<br />

Single Nucleotide Polymorphism (SNP) array. Using Partek Genomic Suite to analyse the<br />

data, our results suggested that deletions on chromosome 6 starting position 19064 KBps<br />

to 73265 KBps and amplifications on chromosome 8 (5501 KBps to 137.1 MBps) were<br />

associated with different stages of albuminuria; most significance being in ESRD. In addition,<br />

there were significant amplifications and deletions (11719 KBps to 124.8 MBps and<br />

132 KBps to 65694 KBps respectively) on chromosome 12 in with macroalbuminuria and<br />

ESRD. The significance of these findings will be discussed.<br />
