Anemia
CUI: C0002871
Disease: Anemia
0.900 GeneticVariation BEFREE The incidence of severe anaemia, ≥ 3 g/dL reduction or <10 g/dL of haemoglobin (Hb) up to week 12, was more frequent in patients with CC at rs1127354 [65% (145/224), 33% (73/224)] than in those with CA/AA [25% (21/85), 6% (8/85)] (P < 0.0001). 24750345 2014
Anemia
CUI: C0002871
Disease: Anemia
0.900 GeneticVariation BEFREE The inosine triphosphatase CC allele (rs1127354) was independently associated with the development of severe anaemia, and lower serum albumin level (<35 g/L) was associated with the occurrence of infection. 24099469 2013
Anemia
CUI: C0002871

0.900 GeneticVariation BEFREE ITPA rs1127354 CA genotype, when compared to CC genotype, was associated with lesser degree of anaemia throughout therapy (P < 0.05 for all time points). 23730840 2013
Anemia
CUI: C0002871
Disease: Anemia
0.900 GeneticVariation BEFREE In conclusion, non-CC at rs1127354 without involvement of rs7270101 is strongly associated with protection from ribavirin-induced anemia, however, ITPA genotype is not associated with SVR. 23960450 2013
