  • Calculating Revised Carrier Risks -- Bayes Analysis
    Bayesian analysis allows one to compare the likelihood of 2 outcomes based on recognized facts. This approach can be used to calculate a variety of probabilities important in medical genetics, including the likelihood of being a carrier following a negative carrier screen. To perform a Bayes analysis in this situation, one must first define the individual's initial carrier risk (prior probability) -- usually based on pedigree calculations or ethnicity data. That initial risk can then be modified based on the negative carrier screen result to determine a revised carrier risk (posterior probability). An example of a common calculation is shown below.

  • Deletion of 8p in a child with normal intelligence-abstract
    The case is presented of a female infant with a distal deletion of 8p (8p23.1-->pter) whose development was monitored over a 5-year period from 12 months of age. Although previous literature has suggested that 8p deletion is associated with mild to moderate intellectual disability, the child reported here has normal intelligence. Despite initial delays in gross motor and language skills, cognitive development (assessed with the Bayley Scales of Infant Development) and intellectual ability (measured on the Stanford-Binet Intelligence Scale) were within average range. It is argued that the small number of previous case reports may have created a misleading impression of intellectual development in individuals with distal deletions of 8p.

  • Ethical Issues With Genetic Testing in Pediatrics
    Advances in genetic research promise great strides in the diagnosis and treatment of many childhood diseases. However, emerging genetic technology often enables testing and screening before the development of definitive treatment or preventive measures. In these circumstances, careful consideration must be given to testing and screening of children to ensure that use of this technology promotes the best interest of the child. This statement reviews considerations for the use of genetic technology for newborn screening, carrier testing, and testing for susceptibility to late-onset conditions. Recommendations are made promoting informed participation by parents for newborn screening and limited use of carrier testing and testing for late-onset conditions in the pediatric population. Additional research and education in this developing area of medicine are encouraged.

  • Polymerase Chain Reaction
    A sample of amniotic fluid yields a small amount of cells and, therefore, DNA. Often when performing genetic testing on amniotic fluid, the first step is to use a technique known as polymerase chain reaction (or PCR) to make many copies of the region of DNA that is of interest, since there are too few to study in the original amniotic fluid sample. This process is called amplification and can be done on DNA extracted from any tissue type. In the case of sickle cell anemia, the beta-globin gene is amplified.

  • Protein Separation
    Proteins, the products of genes, vary from one another by shape, size, charge, molecular affinity, and other characteristics. Proteins made from different genes usually differ from each other in significant ways. However, proteins made by the same gene may also exhibit different characteristics. These differences can be the result of the presence of a genetic mutation. Such differences can be used to identify the presence of normal and abnormal proteins.
  • Protein Truncation Testing
    For mutations that commonly cause shortened (truncated) protein products, protein truncation testing (PTT) can be very useful. In the lab, proteins are artificially synthesized from the gene in question. The protein products are then separated by size on a special gel. A smaller-than-normal protein on the gel indicates the presence of a truncating mutation.

  • Restriction Enzyme Digestion
    Restriction enzyme digestion describes the process used to cut, or digest, large pieces of DNA into smaller pieces. DNA is cut by combining it with a special type of enzyme, a restriction enzyme, which "recognizes" a unique DNA sequence. The mixture is then incubated under laboratory conditions to maximize digestion. During digestion, the enzyme locates places along the DNA with the unique sequence and cuts the DNA at that site.
  • Southern Blotting
    Southern blot analysis involves transferring DNA fragments embedded within a gel (after electrophoresis) onto a special membrane. Because the fragments transferred onto the membrane are too small to be seen, probes created to target a specific DNA sequence must be added. Probes are relatively short stretches of DNA that are tagged, often with fluorescence or radioactivity, allowing them to be visualized when bound to the DNA on the membrane. Probes will only bind or stick to the specific piece of DNA for which they are designed.

    Autism spectrum disorders (ASDs) are a group of developmental disabilities defined by significant impairments in social interaction and communication and the presence of unusual behaviors and interests. Many people with ASDs also have unusual ways of learning, paying attention, or reacting to different sensations. The thinking and learning abilities of people with ASDs can vary – from gifted to severely challenged. ASD begins before the age of 3 and lasts throughout a person's life. It occurs in all racial, ethnic, and socioeconomic groups and is four times more likely to occur in boys than girls. (From Their Website)
