摘要
BackgroundThe presence of deletions can complicate genetic diagnosis of autosomal recessive disease. MethodThe DNA of patients was analyzed in a diagnostic setting. ResultsWe present three unrelated patients each carrying deletions that encompass the 37kb CLN8 gene and discuss their phenotype. Two of the cases were hemizygous for a mutant allele - their deletions unmasked a mutation in CLN8 on the other chromosome. ConclusionMicroarray analysis is recommended in any patient suspected of NCL who is apparently homozygous for a mutation that is not present in one of the parents or when the family has no known consanguinity.
