ABSTRACT
<p><b>OBJECTIVE</b>To detect potential mutation of galactosamine-6-sulfate (GALNS) gene in a Chinese girl affected with mucopolysaccharidosis type IV A (Morquio A syndrome).</p><p><b>METHODS</b>The patient was diagnosed by assaying the activities of mucopolysaccharidosis-related enzymes in leukocytes. Potential mutation in the GALNS gene was detected with PCR and Sanger sequencing.</p><p><b>RESULTS</b>The patient was characterized by short stature, skeletal deformities, normal intelligence, and auditory dysfunction. The activities of GALNS enzymes were low. A compound heterozygous missense mutation, c.1094G>T (p.Gly365Val)/c.938C>T (p.Thr313Met), was detected in the GALNS gene. The mutations were respectively inherited from her father and mother. Among them, the c.1094G>T (p.Gly365Val) mutation was not reported previously.</p><p><b>CONCLUSION</b>The mutations c.1094G>T (p.Gly365Val)/c.938C>T (p.Thr313Met) probably underlie the pathogenesis of the disease in our patient.</p>
