Is albinism substitution deletion or insertion?

Albinism is typically caused by mutations in genes that are involved in the production of melanin, such as the TYR gene. These mutations can be classified as substitutions, deletions, or insertions, depending on the specific alteration in the DNA sequence. The most common mutations associated with albinism are single nucleotide substitutions, but deletions and insertions can also occur. Thus, albinism can arise from various types of genetic mutations, not limited to just one category.
