Introduction. Caregivers of children with chronic illness are at risk of having impairment in their quality of life (QOL). We systematically reviewed the available literature related to the Health Related Quality Of Life (HRQOL) of caregivers of children with Phenylketonuria (PKU). Methods. We comprehensively searched in electronic databases including Scopus, Science Direct, CINAHL, Medline, PubMed, Google scholar, and ProQuest. The search criteria included studies with samples more than one, children suffering from PKU, exploring parents or primary caregiver’s HRQOL, published from 2010 to 2020, full article available for download and published in English. Eight studies including 5 cross sectional studies, 1 open label trial, and 2 surveys were systematically reviewed. Results. Seven out of 8 studies have established a negative correlation between PKU and parent’s HRQOL in at least 1 of the domains. In one study, the HRQOL of parents is higher than their population norms. Conclusion. Most of the caregivers had poor to moderate HRQOL. More studies are required to explore HRQOL of caregivers of children with PKU using similar tools and outcome measures addressing all the domains of HRQOL in order to have more clarity on the impact of PKU on caregiver’s HRQOL. Interventional studies might help in improving the HRQOL of caregivers.
