Analysis of GCDH gene variant in a child with Glutaric aciduria type I / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a neonate affected with Glutaric aciduria type I (GA-I).@*METHODS@#Targeted capture and high-throughput sequencing was carried out for the proband and her parents. Candidate variants were verified by Sanger sequencing.@*RESULTS@#The proband was found to harbor compound heterozygous variants of the GCDH gene, namely c.523G>A and c.1190T>C, which was derived from her father and mother, respectively.@*CONCLUSION@#The compound heterozygous variants of the GCDH gene probably underlay the GA-I in the patient.
