Recorded data were analyzed in Stata-12 software after completion.
Results: Newborns were identified with Phenylketonuria during the years 2006 to 2016 and incidence rate calculated 1.91 per 10,000 live births. The highest incidence rate of disease was 3.86 per 10,000 live births in 2014. Delfan (Nurabad) County and Borujer County had maximum and minimum rate of incidence with 5.94 per 10,000 and 0.64 per 10,000, respectively. Among 74 patients, 42 (56%), were female and there was patients' parental kinship in 82% of parents that about 92 percent of suffering children parents had done genetic consultation.
