<unk> , also referred to as<unk> LT or<unk>  1, is an inherited clotting disorder that primarily affects males. It is a WAS-related disorder, meaning it is caused by a mutation in the Wiskott–Aldrich syndrome (WAS) gene, which is located on the short arm of the<unk>  chromosome. WAS-related disorders include Wiskott–Aldrich syndrome,<unk> LT, and<unk><unk>  congenital neutropenia <unk> LN). Of the WAS-related disorders,<unk>  is considered to be the milder phenotype. Between 1 and 10 per million males worldwide are affected with this disorder. Females may be affected with this disorder but this is very rare since females have two<unk>  chromosomes and are therefore typically carriers of the mutation.
