ABSTRACT
<p><b>OBJECTIVE</b>To review the clinical features of a families affected with glutaric acidemia type I (GA-1) and screen potential mutations in glutaryl-CoA dehydrogenase (GCDH) gene.</p><p><b>METHODS</b>Clinical data of the patients and their family members was analyzed. Genomic DNA was extracted from peripheral blood samples. The 11 exons and flanking sequences of the GCDH gene were amplified with PCR and subjected to direct DNA sequencing.</p><p><b>RESULTS</b>Two patients have manifested macrocephaly. Imaging analysis revealed arachnoid cyst and subdural effusion. The elder sister had encephalopathy crisis. The younger sister had significantly raised glutaric acid, whilst the elder sister was normal during the non-acute phase. Genetic analysis has revealed a homozygous c.1244-2A> C mutation of the GCDH gene in both patients.</p><p><b>CONCLUSION</b>The clinical features and mutation of the GCDH gene have been delineated in a Chinese family affected with GA-1. The c.1244-2A> C mutation may be particularly common in the Chinese population.</p>
