The Levels of Vitamin D Vitamin D Receptor Homocysteine and Complex B Vitamin in Children with Autism Spectrum Disorders

摘要

ObjectiveAutism spectrum disorder (ASD) is a complex neurodevelopmental syndrome with an increasingly prevalent etiology, yet not fully understood. It has been thought that vitamin D, complex B vitamin levels and homocysteine are associated with environmental factors and are important in ASD. The aim of this study was to examine serum vitamin D, vitamin D receptor (VDR), homocysteine, vitamin B6, vitamin B12 and folate levels in ASD.
