ABSTRACT
<p><b>OBJECTIVE</b>To detect potential mutation in a Chinese family affected with succinic semialdehyde dehydrogenase deficiency.</p><p><b>METHODS</b>Genomic DNA was extracted from the peripheral blood samples of the proband, her family members and 100 healthy controls. All exons and flanking intronic regions of the ALDH5A1 gene were amplified by PCR and subjected to direct sequencing.</p><p><b>RESULTS</b>The proband was found to have compound heterozygous mutations of the ALDH5A1 gene, namely c.398_399delAA (p.N134X) and c.638G>T (p.R213L), for which her parents were both heterozygous carriers. The same mutations were not found among the 100 healthy controls.</p><p><b>CONCLUSION</b>The novel mutations of the ALDH5A1 gene probably underlie the pathogenesis of the disease in the infant, which also enriched the mutation spectrum of the ALDH5A1 gene.</p>
