In a recent genome-wide association study (GWAS) conducted by the Australian and New Zealand Multiple Sclerosis Genetics Consortium (ANZgene) [28], several single nucleotide polymorphisms (SNPs) within the MERTK gene (Chromosome 2q14.1, Accession Number NG_011607.1) showed suggestive association with susceptibility to MS, while SNPs within the TYRO3, AXL, GAS6 and PROS1 genes did not show any suggestive associations. Here, GAS6 is linked to myeloid sarcoma.
