Notes

This is apparently the SNP referred to as "g.25498283A>C" (without any GRCh reference provided) in a 2019 publication that reported the rs1419974780(A;A) genotype - which is actually the most common genotype by far - as providing less protection against MRSA infection than the quite rare heterozygote (A;C) genotype. Note that this study should probably be considered preliminary, since it's a first report and it's also based on a relatively small number of patients.
