As a medical expert with a focus on genetics, I'm well-versed in the complexities of genetic disorders. Hemophilia A, a genetic disorder that impairs the body's ability to make blood clots, is indeed characterized by mutations in the gene responsible for the production of clotting factor VIII. This gene is located at the chromosomal locus Xq28. The term "deletion mutation" refers to a type of mutation where a segment of DNA is missing or deleted, and it can indeed be one of the causes of Hemophilia A.
Hemophilia A is typically inherited in an X-linked recessive pattern, which means it is much more common in males than in females. Females have two X chromosomes, while males have only one, so a male with a mutation in his single X chromosome will exhibit symptoms of the disorder. Females, on the other hand, would need to inherit two copies of the mutated gene, one from each parent, to develop the disorder, which is a rare occurrence.
The mutations that can lead to Hemophilia A are diverse and can include point mutations, small insertions or deletions, and larger structural variations such as deletions or duplications. Point mutations are the most common type and can be further classified into missense mutations, which alter a single amino acid in the protein, and nonsense mutations, which introduce a premature stop codon, leading to a truncated and nonfunctional protein.
Large gene deletions are considered severe because they often result in the complete absence of the clotting factor, leading to a more severe form of the disorder. Nonsense mutations are also severe as they prevent the production of any functional protein. Frameshift mutations, caused by insertions or deletions of nucleotides that are not multiples of three, disrupt the reading frame of the gene, resulting in an abnormal protein that is usually nonfunctional.
The severity of Hemophilia A can vary widely, from mild to severe, depending on the type and location of the mutation. Some individuals with mild forms of the disorder may not even be aware that they have it, as their clotting factor levels can be close to normal. In contrast, those with severe forms may experience frequent and spontaneous bleeding episodes.
Diagnosis of Hemophilia A typically involves measuring the levels of clotting factor VIII in the blood. Genetic testing can also be performed to identify the specific mutation causing the disorder. Treatment options include clotting factor replacement therapy, where the missing or deficient clotting factor is infused into the bloodstream, and in some cases, gene therapy, which aims to correct the underlying genetic defect.
In conclusion, Hemophilia A is a complex genetic disorder with a range of mutations that can lead to varying degrees of severity. Deletion mutations are one type of mutation that can cause the disorder and are associated with more severe forms due to the complete absence of functional protein.

Hemophilia A is noted to have a mutation at the chromosomal locus Xq28 and cause an absence of the functional protein made by factor VIII, coagulation factor VIII. ... Mutations that are responsible for severe forms of hemophilia B include large gene deletions, nonsense mutations, and most frameshift mutations.
