Cytogenetic, biochemical, and molecular analyses of a 22q13 deletion.
We report on a 3-year-old boy with a terminal deletion of 22q. The activity of alpha-N-acetylgalactosaminidase was normal while arylsulfatase A activity was reduced. Molecular analysis demonstrated the lack of paternal alleles of D22S45 and D22S55.
