ABSTRACT
OBJECTIVE@#To detect potential variation in glutaryl-CoA dehydrogenase (GCDH) gene among three Chinese families affected with glutaric acidemia type Ⅰ(GA-1) and correlate the genotypes with phenotypes.@*METHODS@#Genomic DNA was extracted from peripheral blood samples derived from three patients with GA-1 and their family members. The coding regions of the GCDH gene were amplified with PCR and subjected to Sanger sequencing.@*RESULTS@#The clinical manifestation of the patients varied from macrocephaly to severe encephalopathy, with notable phenotypic difference between siblings carrying the same variation. In pedigrees 1 and 2, the probands have carried compound heterozygous variations c.1133C>T(p.Ala378Val) and c.1244-2A>C, which were derived their fathers and mothers, respectively. In pedigree 3, the proband has carried compound heterozygous variation c.339delT (p.Tyr113) and c.406G>T (p.Gly136Cys). Among these, variations c.339delT and c.1133C>T were verified as novel by retrieval of dsSNP, HGMD and 1000 genome database. Bioinformatic analysis suggested that above variations can affect protein function and are probably pathogenic.@*CONCLUSION@#Above discovery has expanded the mutation spectrum of the GCDH gene. No correlation was found between the clinical phenotype and genotype of GA-1 patients.
