loss of existing function
Yes, BRCA1 is a tumor suppressor gene.
Yes, a point mutation can result in a frameshift mutation if it occurs in a coding region of a gene and disrupts the reading frame of the genetic code.
A mutation is a change in a DNA sequence that can result in alterations to the structure or function of a gene, potentially leading to different traits or characteristics in an organism.
A permanent change in the sequence of DNA in a gene is called a mutation. Mutations can result from errors in DNA replication, exposure to environmental factors like radiation or chemicals, or as a result of genetic inheritance. These changes can alter the function of the gene and potentially lead to genetic disorders or diseases.

phylogeny
frameshift mutation, which alters the reading frame of the gene. This can result in a nonfunctional or altered protein being produced.
Genetic diseases
A mutation is a change in a DNA sequence that can result in alterations to the structure or function of a gene, potentially leading to different traits or characteristics in an organism.
A point mutation, specifically a substitution mutation, is when only one nucleotide base is altered in a gene sequence, affecting one codon. This can result in a change in the amino acid encoded by that codon in the mRNA, impacting the protein produced by the gene.
A permanent change in the sequence of DNA in a gene is called a mutation. Mutations can result from errors in DNA replication, exposure to environmental factors like radiation or chemicals, or as a result of genetic inheritance. These changes can alter the function of the gene and potentially lead to genetic disorders or diseases.
A change in a gene due to damage or being copied incorrectly is called a mutation. This alteration can result in changes to the gene's function or produce new traits in an organism.
A mutation
APC is classified as a tumor suppressor gene. Tumor suppressor genes prevent the uncontrolled growth of cells that may result in cancerous tumors. The protein made by the APC gene plays a critical role in several cellular processes that determine whether a cell may develop into a tumor.
