Answer #1

Exome sequencing or whole exome sequencing( WES) is defined as sequencing of the exons or protein coding sequence alone. Sequencing only the functional genes gives more clear idea of disease candidate genes. Autism is a neurodevelopmental disorder in which social interaction and communication deficits occurs. Genes responsible for the neurological deficit can be identified through the exome sequencing. Through exome sequencing of samples from patients having autism led to discovery of gene variants that are responsible for autism spectrum disorders. Following are the genes identified in whole exome sequencing of autism patient samples using Sanger sequencing : PTEN, AFF2, ADNP, IL1RAPL1, CHD8, SHANK3 and POGZ.

Eventhough there are patients without the above gene variants are available, above are the mostly commonly occuring disease variants .

    DNA sequencing of the human genome suggests that humans have --25,000 genes. However, the proteome (the entire set of proteins expressed by an organism) of humans is considerably larger. Explain briefly how this is possible. Additional Information. Below is a codon table, which you may consult if you need to.

    A team of researchers has conducted an exome sequencing study to find the causative mutation for a rare mendelian disease. All known cases have had an affected parent and it is likely that the disease is dominant. After comparing the exome sequences from four different patients, the researchers find that nine different genes have a potentially harmful mutation in all four patients under the dominant model. As expected no single mutation under the recessive model is shared by all four...
