Chapter 17, Problem 20P
Hydatiform moles are growths of undifferentiated tissues that form within the uterus during an abnormal molar pregnancy. These moles are usually made up of XX diploid cells, although some can be XY diploids. Surprisingly, all of the DNA in the nuclei of the cells in the mole is paternal in origin. Most hydatiform moles are benign, but because they sometimes can develop into cancers, these moles should be removed surgically when they are detected.
| a. | What kinds of events could lead to the generation of a hydatiform mole? |
| b. | Hydatiform moles are diploid cells with the normal numbers of genes and chromosomes. Why do you think they develop as undifferentiated tissues rather than as normal embryos? |

The woman in Problem 24 has had two miscarriages. She has come to you, an established genetic counselor, with these questions: Is there a genetic explanation of her frequent miscarriages? Should she abandon her attempts to have a child of her own? If not, what is the chance that she could have a normal child? Provide an informed response to her concerns.
Campomelic dysplasia (CMD1) is a congenital humansyndrome featuring malformation of bone and cartilage.It is caused by an autosomal dominant mutation of agene located on chromosome 17. Consider the followingobservations in sequence, and in each case, draw whateverappropriate conclusions are warranted.(a) Of those with the syndrome who are karyotypically46,XY, approximately 75 percent are sex reversed,exhibiting a wide range of female characteristics.(b) The nonmutant form of the gene, called SOX9, isexpressed in the developing gonad of the XY male,but not the XX female.(c) The SOX9 gene shares 71 percent amino acid codingsequence homology with the Y-linked SRY gene.(d) CMD1 patients who exhibit a 46,XX karyotypedevelop as females, with no gonadal abnormalities.

- A woman is affected with Prader-Willi syndrome due to a deletion that includes both the Angelman syndrome and Prader-Willi syndrome genes. Although rare, fertility among Prader-Willi syndrome individuals has been documented. For each of the following, state what is the probability of the outcome if she were to become pregnant. Assume the male partner in the pregnancy has no genetic disorder. A) a child with neither Prader-Willi syndrome or Angelman syndrome B) A child with AS C) A child with Prader-Willi syndromearrow_forwardFamilial retinoblastoma, a rare autosomal dominant defect, arose in a large family that had no prior history of the disease.

- Neurofibromatosis 1 is considered an autosomal dominant disorder because the gene is located on the long arm of chromosome 17. It is caused by microdeletion at the long arm of chromosome 17 band 11 sub-band 2 involving the NF1 gene. Group of answer choices Statement 1 is correct. Statement 2 is incorrect Statement 1 is incorrect, statement 2 is correct Both statements are incorrect Both statements are correctarrow_forwardThe following pedigree illustrates the inheritance of Nance–Horan syndrome, a rare genetic condition in which affected people have cataracts and abnormally shaped teeth.arrow_forwardSix months pregnant, an expectant mother had a routineultrasound that showed that the limbs of the fetus wereunusually short. Her physician suspected that the babymight have a genetic form of dwarfism called achondroplasia,an autosomal dominant trait occurring with a frequency of about1 in 27,000 births. The parents were directed to a genetic counselorto discuss this diagnosis. In the conference, they learnedthat achondroplasia is caused by a mutant allele. Sometimes itis passed from one generation to another, but in 80 percent ofall cases it is the result of a spontaneous mutation that arisesin a gamete of one of the parents. They also learned that mostchildren with achondroplasia have normal intelligence and a normallife span. What information would be most relevant to concluding whichof the two mutation origins, inherited or new, most likelypertains in this case? How does this conclusion impact on thiscouple’s decision to have more children?arrow_forward

Dystrophin is a protein encoded by a single gene, DMD, that is expressed in skeletal and cardiac muscle. Some forms of muscular dystrophy may be caused by different mutations in the DNA sequence of the DMD gene. Because the DMD locus is on the X chromosome, males are affected at higher rates. Two brothers, one of whom has DMD and one of whom does not, worked with their genetic counselor (Links to an external site.) to have their DMD gene sequenced to identify genetic variation that may explain why one brother was affected and the other not. Because DMD is a very long gene, a fictionalized, simplified model of the results is presented here (Figure 1). The actual DMD mRNA is about 16,000 base-pairs!------Consider single nucleotide polymorphism (SNP) #1 (Figure 1).

- Please summarize and make the following paragraph about treacher collins syndrome disease into important bullet points. Thank you!! A mutation in the TCOF1 gene causes up to 93% of Treacher Collins syndrome cases. This gene, which is found on chromosome 5, is in charge of facial developnent. TCOF1 changes spontaneously in around half of all cases at conception, but no one knows what causes the change. In addition, Treacher Collins syndrome is inherited as an autosomal dominant condition in some cases. This indicates that the child inherits the Treacher Collins syndrome gene from one parent and an unaffected copy from the other. Changes in the POLRIC and POLRID genes may be responsible for another 2% of instances. It's unclear how the mutations in the genes create facial abnormalities. However, during weeks three to eight of embryonic development, they are thought to trigger apoptosis (cell death) of facial bone, cartilage, and soft tissue.arrow_forwardA boy with Klinefelter syndrome (47,XXY) is born to a motherwho is phenotypically normal and a father who has the X-linkedskin condition called anhidrotic ectodermal dysplasia. The mother’sskin is completely normal with no signs of the skin abnormality.In contrast, her son has patches of normal skin and patchesof abnormal skin. Using the appropriate genetic terminology, explain theson’s skin phenotype.arrow_forwardThe following Pedigree shows an unknown genetic disorder. The disorder is believed to be caused by single gene mutations. For the following disorder, determine whether the mutant gene is located on an autosome or X chromosome. arrow_forward
