摘要：
Aspartylglucosaminuria (AGU) is a recessive autosomally inherited lysosomal storage disorder due to deficiency of the enzyme aspartylglucosaminidase (AGA). The structural gene for this human enzyme (AGA) has been assigned to the region 4q21-->qter. We determined the AGA activity in cultured fibroblasts of a girl with a 46,XX,del(4)(q33) karyotype. The results indicate that the girl is a hemizygote for AGA, permitting the assignment of human AGA to the region 4q33-->qter.
