Point mutation brings little phenotypic change as compared to frameshift mutation. Applications include detection of a mutation in the human homologue of the PAX-3 paired box gene in Waardenburg's syndrome (Tassebehji et al., 1992) and rhodopsin mutations in retinitis pigmentosa (Keen et al., 1991b).

April 16, 2017 Detection of unknown mutations can involve sequencing of kilobases of DNA, often in many patients. The missense mutation causes phenotypic change in organism. It is the mutation in which mutated codon codes same amino acids as the original codon. Such incomplete protein is always non-functional.
