mother. For both types of diabetes. Leigh’s syndrome Leber’s hereditary neuropathy is a mitochondrial disorder that leads to a rapid onset of vision loss. MELAS syndrome C.Concordance rates of 80% were observed for NIDDM. researchers calculated concordance rates for monozygotic (MZ) twins. Based on this information. NIDDM appears to due tomutations in a single. The concordance rates are lower than those values for this study. what is the genotype of Michael at the ABO blood group locus? A. Question 44 The ABOblood group is coordinated by three alleles (A. However. E. BO . AO D. The most likely explanation is that the variant is in linkage disequilibrium with a nearby functional change that
increases the risk of ADHD (see Chapter 9). Genetic influences exert a larger role in NIDDM than in IDDM. there is a substantial concordance for NIDDM among MZ twins. Question42 A 19-year-old male patient complains of a loss of central vision in both eyes. suggesting that genetic factors play a potentially larger role in the etiology of this disorder (seeChapter 15). NIDDM is primarily determined by non-genetic factors D. all her five siblings. etiology of the disorder The variant in the dopamine transporter does not appear likely to bea functional cause of the disorder because neither allele appears to influence the transporter activity. Question 43 In an effort to identify the influence of genetic factors on bothinsulin-dependent (IDDM) and non-insulin- dependent (NIDDM) diabetes mellitus. Leber’s hereditary neuropathy D. B. AA E. The onset was less than 6 months ago and hasprogressed rapidly. dizygotic (DZ) concordance rates were 15%. and the proband’s maternal grandmother. You develop a differential diagnosis of likely disorders that includes whichof the following? A. AB C. Concordance rates of 30–50% have been found for IDDM. Genetic factors have little or no role in the etiology of IDDM C. The following pedigree shows theblood groups from a three-generation family. OO B. gene Twin studies are ofen used in an attempt to identify the degree of genetic influence exerted on a disorder. indicating thatthere is also a role for non- genetic (environmental) factors in the etiology of NIDDM and IDDM. Kearns-Sayre syndrome E. and both are dominant to the O allele. What does thisinformation suggest concerning the relative effect of genetic and environmental factors for each type of diabetes? A. No conclusions can be drawn from this study B. as yetunidentified. concordance rates would approach 100% for MZ twins and 50% for DZ twins. The code is overlapping C. Other sequences (like introns) are transcribed. Ofen. leading toincorporation of incorrect amino acids E. The code is degenerate B. The first child has type A blood. it cannot be added to the polycystin transcript B. Depending on their specificgenotypes. these are removed during RNA processing E. the genetic code is said to be degenerate (see Chapter 2). DNA contains non-coding sequences. AO or OO.g. Question 47
