The rs2229611 (G6PC:c.*23 T>C) is associated with glycogen storage disease type Ia in Brazilian patients

The rs2229611 SNP (G6PC:c.*23T>C) in the 3’UTR region of the G6PC gene affects the stability of the glucose-6-phosphatase mRNA and occurs in a higher frequency in patients with glycogenosis Ia (GSD Ia) in some populations. Herein, a group of Brazilian patients (n = 116) was analyzed by NGS and the frequency of rs2229611:T>C was determined. The linkage disequilibrium (LD) between pathogenic variants and the rs2229611:T>C SNP was evaluated. The results showed that the rs2229611:T>C is associated to GSD Ia and is in LD with the most frequent pathogenic variants in Brazilian patients with GSD Ia.
