From previous studies in Javanese Indonesians and Malays, which are anthropologically closely related with Bengkulu Indonesians, the frequency of mutation of UGT1A1*6 (0.015 and 0.014) is quite low and does not differ significantly between normal bilirubin level and hyperbilirubinemia neonates [7]. The gene discussed is UGT1A1; the disease is Hyperbilirubinemia.
