ARLTS1, a member of the Ras superfamily and putative tumor-suppressor gene resides at chromosome 13q14, a region commonly deleted in hematopoietic and solid tumors. Previously, the truncating single nucleotide polymorphism (SNP) of ARLTS, G446A (W149X) has been reported to act as a multi-site tumor susceptibility allele. To explore the relationship between polymorphic variation in ARTLS1 and risk of chronic lymphocytic leukemia (CLL) we analyzed germline DNA from 413 cases and 471 healthy controls for W149X and five additional coding SNPs, S99S, P131L, L132L, C148R, and E164K. A high proportion of the cases were familial, thereby empowering detection of an association. None of the SNPs were individually significantly associated with risk of CLL and there was no evidence for epistatic interaction between loci. Our study does not support the postulate that variants of ARLTS1 influence the risk of CLL.
