Aims: NAS incidence & severity in infants exposed to methadone during gestation is independent of maternal methadone dose. The incidence & severity of NAS could be in part due to genetic variability of key genetic loci related to opioid response; the interleukin-1beta (IL-1B) & mu opioid receptor (OPRM1) genes. This study aimed to investigate the impact of genetic variability in IL-1B -31 or OPRM1 A118G on NAS incidence (treatment required) & severity (dose of morphine).
Methods: This pilot study collected cheek cells from 71 methadone exposed infants; 46 …
