Lesch-Nyhan syndrome is due to a mutation in a gene that encodesa protein called hypoxanthine-guanine phosphoribosyltransferase(HPRT). HPRT is an enzyme that functions in purine metabolism.People afflicted with this syndrome have severe neurodegenerationand loss of motor control. The pedigree below contains severalindividuals with Lesch-Nyhan syndrome, shown with blacksymbols. Based on this pedigree, does this syndrome appearto be inherited by an autosomal recessive, autosomal dominant,X-linked recessive, or X-linked dominant pattern? Explainyour reasoning.
Sandhoff disease is due to a mutation in a gene that encodes a proteincalled hexosaminidase B. This disease has symptoms that aresimilar to those of Tay-Sachs disease. Weakness begins in the first 6 months of life. Individuals exhibit early blindness and progressive mental and motor deterioration. The family in the pedigree shown below has three members with Sandhoff disease, indicated with black symbols.
Huntington disease (HD) is an inherited neurodegenerative disorder characterized by gradual, irreversible impairment of psychological, motor, and cognitive functions. Symptoms typically appear in middle age, but onset can occur at almost any age, and the course of the disease can range from 15 to 20 years. The molecular basis of HD is becoming better understood, and the genetic mutation has been traced to a gene that encodes a large protein of unknown function. In individuals who will not develop HD, a region of the gene that encodes the N-terminus of this protein has a sequence of CAG codons (for glutamine) repeated 6 to 39 times in succession. In individuals with adult-onset HD, this codon (3 nucleotides) is typically repeated 40 to 55 times In those with childhood-onset HD, it is repeated more than 70 times. *codon: refers to the 3 nucleotides that code for amino acid. A small portion of the coding sequence of the HD gene is given below. The nucleotide sequence of the DNA is…
Gene A, which encodes alcohol dehydrogenase, is labeled with a red fluorophore in a FISH experiment with one chromosome of a homologous pair, with results shown below. Gene B is labeled in green and encodes Notch2NL, a gene which may help to explain brain size differences between humans and chimpanzees, and which with increased dosage, may lead to a condition referred to as macrocephaly (enlarged head circumference sometimes associated with learning disabilities). What can you infer about these two genes given the results seen below?
Duchenne muscular dystrophy (DMD) is an X-linked recessive genetic disease caused by mutations in the gene that encodes dystrophin, a large protein that plays an important role in the development of normal muscle fibers. The Dystrophin gene is immense, spanning 2.5 million base pairs, and includes 79 exons and 78 introns. Many of the mutations that cause DMD produce premature stop codons, which bring protein synthesis to a halt, resulting in a greatly shortened and nonfunctional form of dystrophin. Some geneticists have proposed treating DMD patients by introducing small RNA molecules that cause the spliceosome to skip the exon containing the stop codon (A. Goyenvalle et al., 2004. Science 306:1796–1799). The introduction of the small RNAs will produce a protein that is somewhat shortened because an exon is skipped and some amino acids are missing, but it may still result in a protein that has some function. The small RNAs, antisense RNAs, used for exon skipping are complementary to…

. The physicist Stephen Hawking, famous for his theories about black holes, has lived past the age of 70 withamyotrophic lateral sclerosis (ALS), a paralyzing neurodegenerative disease that is usually fatal at a muchyounger age. Recently, geneticists discovered that amajor cause of ALS is the unusual expansion of ahexanucleotide repeat (5′-GGGGCC-3′) that lieswithin a gene called C9ORF72, at a location outside ofthe gene’s open reading frame (ORF). A single expanded allele is sufficient to cause ALS, but the reasonthe disease allele is dominant remains unclear. Someexperimental results support the theory that the allelemakes a toxic RNA containing the expanded repeat. Ifthis theory is correct, in what ways is the mutant ALScausing allele similar to the mutant allele that causesHuntington disease? In what ways is it similar to themutant allele that causes fragile X syndrome?
In a study of a muscle disorder, several affected families exhibited vision problems, muscle weakness, and deafness (M. Zeviani et al. 1990. American Journal of Human Genetics 47:904–914). Analysis of the mtDNA from affected members of these families revealed that large numbers of their mtDNA molecules possessed deletions of varying lengths. Different members of the same family and even different mitochondria from the same person possessed deletions of different sizes, so the underlying defect appeared to be a tendency for the mtDNA of affected persons to have deletions. A pedigree of one of the families studied is shown below. The researchers concluded that this disorder is inherited as an autosomal dominant trait, and they mapped the diseasecausing gene to a position on chromosome 10 in the nucleus. Q. What characteristics of the pedigree rule out inheritance of a trait encoded by a gene in the mtDNA as the cause of this disorder?
