ABSTRACT
BACKGROUND:
The incidence of inborn errors of metabolism varies widely across countries. Very few studies have analyzed the incidence of these disorders in Mainland China. We aimed to estimate the overall and disease-specific incidences of inborn errors of metabolism in Chinese newborns and investigate the geographical distribution of these disorders.METHODS:
A national cross-sectional survey was conducted to investigate newborn inborn errors of metabolism screening by tandem mass spectroscopy in Mainland China between 2016 and 2017. A total of 246 newborn screening centers were surveyed using a standardized questionnaire. We examined the cumulative and disease-specific incidences of inborn errors of metabolism in Mainland China as a whole and in different geographical locations.RESULTS:
Over 7 million newborns were screened and 2747 were diagnosed with inborn errors of metabolism, yielding an overall incidence of 38.69 per 100,000 births (95% confidence interval 37.27-40.17). The most common disorders were amino acid disorders (17.14 per 100,000 births, 95% confidence interval 16.21-18.13), followed by organic acid disorders (12.39 per 100,000 births, 95% confidence interval 11.60-13.24) and fatty acid oxidation disorders (9.16 per 100,000 births, 95% confidence interval 8.48-9.89). The overall and disease-specific incidence rates differed significantly across geographical locations (P < 0.001).CONCLUSIONS:
The overall incidence of inborn errors of metabolism in Chinese newborns is relatively high. It is urgent to establish the recommended uniform screening panel for inborn errors of metabolism to guide the national and regional tandem mass spectroscopy newborn screening programs.Palavras-chave
