This gene sees a mutation at amino acid 282 where there is a substitution of tyrosine for cysteine in the protein product. The homozygous YY (AA) genotype is the risk genotype. WebThe most important is a single mutation of G to A at nucleotide 845, resulting in the substitution of tyrosine for cysteine at amino acid 282. This is known as the Cys282Tyr or C282Y mutation. The second mutation identified was of C to G at nucleotide 187, resulting in a substitution of aspartate for histidine at amino acid 63. great meteor hotspot track
