Mucopolysaccharidosis IVA (MPS TVA) is an autosomal recessive disorder caused by a deficiency in N-acetylgalactosamine-6-sulfatase (GALNS). We found two separate deletions of nearly 8.0 and 6.0 kb in the GALNS gene, including some exons. There are Alu repetitive elements near the breakpoints of the 8.0-kb deletion, and this deletion resulted from an Alu-Alu recombination. The other 6.0-kb deletion involved illegitimate recombinational events between incomplete short direct repeats of 8 bp at deletion breakpoints. The same rearrangement has been observed in a heteroallelic state in four unrelated patients. This is the first documentation of a common double deletion a gene that is not a member of a gene cluster. (C) 1995 Academic Press, Inc.
