Deletion mutations of WAS are relatively rare and the precise localization of large deletions in the genome has rarely been described in previous studies. We report here a 5-month-old boy with a large deletion mutation inWAS that completely abolished protein expression. To localize the deletion, a 2816-bp-length sequence that spans between exons 9 and 12 was amplified. PCR amplification of the patient's sample revealed a single band of about 1kb in contrast to the 2816-bp-amplicon in the control. Genomic DNA sequencing of the patient revealed a 1595-bp-deletion and an adenine insertion (g.5247_6841del1595insA). This large deletion of WAS resulted in partial loss of exon 10 and intron 11, and a complete loss of intron 10 and exon 11.
