    • Abstract:
      Objective: To explore the clinical features and genetic basis for a child with early-onset Isolated sulfite oxidase deficiency (ISOD).
      Methods: A child with ISOD who was admitted to Weihai Hospital Affiliated to Qingdao University on May 10, 2020 was selected as the study subject. Clinical data of the child was analyzed. The child and her parents were subjected to trio-whole exome sequencing, and candidate variants were verified by Sanger sequencing.
      Results: The female neonate was transferred to the intensive care unit due to "secondary pollution of amniotic fluid and laborious breathing for 11 minutes", and had developed frequent convulsions. Genetic testing revealed that she has harbored c.1200C>G and c.188G>A compound heterozygous variants of the SUOX gene, which were inherited from her mother and father, respectively. The c.1200C>G has been described previously and was rated as pathogenic based on guidelines from the American College of Medical Genetics and Genomics, whilst the c.188G>A variant was unreported previously and rated as variant of unknown significance.
      Conclusion: The compound heterozygous variants of the SUOX gene probably underlay the ISOD in this child. Above finding has enriched the spectrum of SUOX gene variants and provided a basis for the clinical diagnosis and genetic counseling.
