The (C) allele of rs6897932, located in the alternatively spliced exon 6 of IL7RA gene and encoding the amino acid threonine rather than isoleucine at amino acid position 244, is associated with a slight increase (18%) in risk of developing multiple sclerosis. [PMID 17660817; Nature Genetics 39, 1083 - 1091 (2007) SG Gregory et al.]
Note that the (C) allele is the most common at this position in all known populations and influences the ratios of the alternative isoforms (membrane bound and soluble) of the gene. Thus, we consider the (T) allele protective.
