This page doesn't give an amino acid change for this particular SNP, so I would then check it's location in the UCSC genome viewer (the hg19/GrCh37.13 version of the genome is still the most useful to use, even though it's not the most recent). The location is chr11:57359802
This shows the SNP to be about halfway between the genes UBE2L6 and SERPING1, therefore it does not change any protein sequence. If this is truly linked to disease it must be via a regulatory function, or is possibly in linkage disequilibrium with a different functional variant.
