ABSTRACT
OBJECTIVE@#To analyze the clinical and genetic characteristics of a patient with dihydrolipoamide dehydrogenase deficiency.@*METHODS@#Potential variants of the DLD gene were detected by whole exome sequencing and verified by Sanger sequencing.@*RESULTS@#Compound heterozygous variants, c.704_705delTT (p.Leu235Argfs*8) and c.1058T>C (p.Ile353Thr), were detected in the DLD gene. The c.1058T>C (p.Ile353Thr) variant was derived from his mother and known to be pathogenic. The c.704_705delTT (p.Leu235Argfs*8) variant was derived from his father and was unreported previously.@*CONCLUSION@#The compound heterozygous variants of c.704_705delTT (p.Leu235Argfs*8) and c.1058T>C (p.Ile353Thr) of the DLD gene probably underlay the disease in this patient. Above finding has facilitated genetic counseling and prenatal diagnosis for the family.
