WebOct 11, 2024 · PLP1 is located on the X-chromosome and encodes myelin proteolipid protein (PLP), the most abundant protein in central nervous system myelin. Generally, point mutations in PLP1 result in X-linked dysmyelinating disorders, such as Pelizaeus-Merzbacher disease (PMD) or spastic paraplegia type 2 (SPG2). However, several case … WebA point mutation is a change to single DNA letter. They fall into three categories: Missense mutations cause a single amino acid change in the protein. Nonsense mutations make a premature "stop" codon. Any codons after that are not translated, and the resulting protein is missing amino acids. Silent mutations code for the same amino acid as before. port townsend high school sports

WebIn some silent mutations the codon codes for a different amino acid that happens to have the same properties as the amino acid produced by the wild type codon. Missense mutations involve substitutions that result in functionally different amino acids; these can lead to alteration or loss of protein function. WebJul 5, 2024 · The melanocytes of wild -type (nonmutant) mice produce more pheomelanin than eumelanin. The result is a sandy -colored mouse. The mutated version of the Mc1r gene, however, triggers melanocyt es to increase the production of eumelanin, resulting in the dark coat -color phenotype.
