Mutations

SNP-id codon number mutation codon mutation triplet aa propensity consequences
rs121907979 39 Leu -> Arg CTT -> CGT aliphatic, hydrophobic, neutral -> positive charged, polar, hydrophilic Leucine is smaller and without a positive charge. Therefore, Arg is too big for the position of Leu, therefore, the change of Leu with Arg has to cause changes in the 3D structure of the protein. Furthermore, Leu is a hydrophobic amino acid, whereas Arg is hydrophilic. This is the complete contrary and therefore we suggest, that the protein will not function any longer.
rs11551324 109 Thr -> Thr ACC -> ACT polar, small, hydrophilic, neutral -> polar, small, hydrophilic, neutral no consequences -> silent mutation
rs61731240 179 His -> Asp CAT -> GAT aromatic, positive charged, polar, hydrophilic -> negative charged, small, polar, hydrophilic On the one side, both amino acids are polar, but on the other side, His is positively charged, while Asp is negatively charged, which is an essential difference between these both amino acids. Therefore it is very likely, that this change causes big changes in the structure of the protein and the protein therefore will probably not work any longer. Furthermore, the structure of the two amino acids is very different, because of the aromatic ring of the His.
rs121907974 211 Phe -> Ser TTC -> TCC aromatic, hydrophobic, neutral -> polar, tiny, hydrophilic, neutral Phe is much bigger than Ser and also contains an aromatic ring. Furthermore, Phe is hydrophobic, whereas Ser is hydrophilic. Because of this, the structure of the protein will change surely and we suggest, that the protein will not work any longer.
rs1054374 293 Ser -> Ile AGT -> ATT polar, tiny, hydrophilic, neutral -> aliphatic, hydrophobic, neutral Ile is much bigger than Ser and also is branched, because it is an aliphatic amino acid. Therefore the structure of both amino acids is really different and Ile is to big for the position where Ser was. Therefore, there has to be a big change in the 3D structure of the protein and the protein probably will loose its function.
rs28942072 324 Val -> Val GTT -> GTA aliphatic, hydrophobic, neutral -> aliphatic, hydrophobic, neutral no consequences -> silent mutation
rs121907967 329 Trp -> TER TGG -> TAG aromatic, polar, hydrophobic -> TER By this change, the protein is not complete, therefore it is not possible for the protein to fold and to function.
rs121907982 436 Ile -> Val ATA -> GTA aliphatic, hydrophobic, neutral -> aliphatic, hydrophobic, neutral In this case, the pysicochemical properties are equal. Furthermore, they almost agree in their size. Therefore, we suggest, that there is no big effect on the 3D structure of the protein and therefore, also no big effect on the protein function.
rs121907968 485 Trp -> Arg gTGG -> CGG aromatic, polar, hydrophobic, neutral -> positive charged, polar, hydrophilic Trp is very big, because of two aromatic rings in its structure. Furthermore, it is hydrophobic, whereas, Arg is a hydrophilic amino acid. Therefore, the changes in the 3D structure might be extreme and delete the function of the protein.
rs4777502 506 Glu -> Glu GAG -> GAA negative charged, polar, hydrophilic -> negative charged, polar, hydrophilic no consequences -> silent mutation
