What chromosome is the gene of bipolar on?
bipolar susceptibility can be linked to small mutations in chromosomes 4,13,15,18, and 22.
What DNA mutations are directly linked to inherited diseases?
Some common DNA mutations directly linked to inherited diseases include the CFTR gene mutation in cystic fibrosis, the BRCA gene mutations in breast and ovarian cancers, and the HTT gene mutation in Huntington's disease. These mutations can be inherited from one or both parents and increase the likelihood of developing the associated disease.
What is the original source of all the different alleles of a genes?
Mutations are the original source of all the different alleles of a gene. Mutations can arise spontaneously during DNA replication or can be induced by environmental factors such as radiation or chemicals. Each mutation creates a new allele with a slightly different sequence from the original gene.
Where is the gene for Btk?
The gene for Btk (Bruton's tyrosine kinase) is located on the X chromosome at position Xq21.32. Mutations in the Btk gene can lead to X-linked agammaglobulinemia, a primary immunodeficiency disorder.
What are three main types of gene mutations what happens in each gene?
The three main types of gene mutations are point mutations, insertion mutations, and deletion mutations. Point mutations involve changes to a single nucleotide base. Insertion mutations involve the addition of extra nucleotide bases. Deletion mutations involve the removal of nucleotide bases in a gene sequence.

What is the mild form of Wiskott-Aldrich syndrome?
The mild form, X-linked thrombocytopenia, is also caused by mutations in this same gene.

What is the most common known cause of genetically linked anomalies?
The most common known cause of genetically linked anomalies is mutations in the DNA sequence. These mutations can be inherited from parents or can occur spontaneously. Errors in the DNA sequence can lead to a range of genetic disorders and anomalies.
What is the cause of improper functions of a gene?
gene mutations
Different forms of a gene are called what?
Different forms of a gene are called alleles. Each allele represents a specific version of a gene that can result in different traits or characteristics.
What is an allele inherited on a sex-chromosome?
A gene found on a sex chromosome is known as a sex-linked gene. Alleles are the different forms of a gene.
What is driver mutation?
The mutations that confer a selective growth advantage to the tumor cell are called “driver” mutations. It has been estimated. A driver gene is one that contains driver gene mutations. But driver genes may also contain passenger gene mutations A typical tumor contains two to eight of these "driver gene" mutations; the remaining mutations are passengers that confer no selective growth advantage.
Name two major types of mutations What do they have in common How are they different Give an example of each?
Gene and chromosomal; both change DNA sequence that affects genetic information. Gene mutations involve a change in one ore several nucleotides in a single gene, whereas chromosomal mutations involve changes in the number or structure of whole chromosomes
